Important medical and commercial notice: Dr. Shape is a postoperative-garment retailer—not a physician, medical practice, healthcare provider or emergency service. This article contains general informational commentary, plain-language summaries of cited third-party sources and product-category information only; nothing in it is a medical opinion from Dr. Shape or individualized medical advice, diagnosis, treatment, a prescription or a recommendation that any product is safe or appropriate for you. Reading this article, contacting Dr. Shape or purchasing a product does not create a physician-patient or other healthcare-provider relationship. Always follow your treating surgeon’s written postoperative plan. If anything here conflicts with that plan, disregard this article and follow the surgeon’s instructions. Do not begin, stop or change a garment, compression level, size, product, placement or wear schedule based on this article. Do not use Dr. Shape content or products to diagnose or treat a symptom or skin condition. Unless your treating surgical team expressly approves the exact item and placement, do not place a garment or accessory directly over an open or unhealed incision, wound, drain, dressing, rash, broken or irritated skin, or an area with new pain, numbness, discoloration or temperature change. Recovery needs and results vary; no medical, healing or cosmetic outcome is promised or guaranteed. Contact your surgical team about questions, symptoms or recovery changes, and seek prompt medical or emergency care when appropriate.
The direct answer is: use the sizing method for the exact faja you are considering and use current—not remembered or aspirational—information. Do not deliberately choose a smaller size to create “more compression.” If the garment is part of postoperative care, the treating surgeon’s written size, pressure, coverage and layer instructions override a general online chart.
Dr. Shape’s current size chart uses current body weight for the listed body garments, compression vests and individual sleeves. It uses a separate underbust method for surgical bras. Another brand or product may use waist, hips, torso length or a different system, so a size from one garment is not automatically transferable to another.
Why faja sizing is product-specific
Letters such as S, M, L or XL are labels, not universal measurements. Two products marked “medium” can differ in stretch, panel construction, torso length, leg opening, closure placement and intended coverage. Stage terminology also does not determine body size. A Stage 2 label is not an instruction to buy smaller than a Stage 1 garment.
Always begin on the exact product page or the chart linked by that product. Confirm that the chart applies to the same model, stage and body area. If the product page and a general store chart appear to conflict, stop and ask the retailer before ordering.
How Dr. Shape currently sizes listed body garments
For the items identified on its size page, Dr. Shape currently directs shoppers to use current body weight. The page specifically says not to use height, regular clothing size or a smaller size chosen for stronger compression. It also directs a shopper whose current weight falls between two listed body-garment sizes to choose the larger listed size.
That is a product-specific retail rule, not a prescription for every manufacturer or postoperative patient. A treating physician may supply different instructions based on the procedure, swelling, layers, drains or other clinical considerations. Follow those instructions instead of this article or the general chart.
Current information matters
Postoperative bodies and garments do not always match preoperative expectations. Current weight, swelling, dressings, foam, boards and other approved layers can change how a garment occupies space. A pre-surgery clothing size or an old faja size may therefore be unreliable.
Use the information requested by the exact chart at the time you are ordering. Do not subtract pounds, pull a tape tightly or choose a hoped-for future measurement. A chart cannot help if the input is intentionally changed.
What about waist, hip and torso measurements?
Some brands and garment models use waist, hip, underbust, thigh or torso measurements. Those measurements can help when the applicable chart requests them, but they should not be substituted into a weight-only chart.
If a chart does request measurements:
- Use a flexible tape and follow the diagram for the exact landmarks.
- Keep the tape level and comfortably against the body rather than pulling it tight.
- Measure over the type of layer specified by the manufacturer.
- Record the current result instead of relying on a past clothing size.
- Ask for help if you cannot reach or see the measuring point accurately.
Torso length and hip-to-waist proportions may also explain why a size that matches one number still feels wrong in a particular design. A retailer’s sizing team can help compare construction, but postoperative suitability remains a question for the treating team.
Surgical bras use a different method
Dr. Shape’s current size page treats its surgical bra as an exception to the weight-based body-garment chart. The page directs shoppers to use the band-size number and provides an underbust measurement chart when the usual band size is unknown. The cup letter is not used as the selected Dr. Shape bra size under that specific method.
Do not use the bra method for a faja, vest or sleeve. Likewise, do not use body weight to select a product whose exact chart requires an underbust, waist, hip or another measurement.
Why sizing down is not a compression strategy
Size and compression specification are different. A smaller body size does not convert one product into another recovery stage or a medically prescribed pressure. Deliberate undersizing can make closures harder to align, concentrate pressure at edges, create rolling or bunching and reduce comfort or movement.
The 2023 practical review of postoperative compression garments describes heterogeneous evidence across procedures and notes potential problems including discomfort and skin defects. It also reports that poor garment fit has been observed in the literature. Those findings support a cautious, product-specific approach rather than a “tighter is better” rule.
Check the whole garment, not just the size label
A size result is only the beginning. Compare the approved product’s physical coverage and where its features will sit:
- Top and bottom edges
- Shoulder straps and arm openings
- Waist, hip and thigh panels
- Zippers, hooks or hook-and-loop closures
- Crotch or bathroom-access design
- Seams near sensitive or treated areas
- Space for surgeon-approved dressings, foam or boards
- Areas intended to receive or avoid pressure
For postoperative wear, the surgeon should approve those details. A chart cannot see an incision, drain, dressing or area of altered sensation.
How should a correctly selected faja feel?
General fit language such as “snug” or “even” is not a medical pressure specification. A garment should not require you to ignore breathing difficulty, worsening pain, persistent numbness, marked discoloration, unusual temperature change, broken skin or another concerning symptom. Contact the treating team promptly about symptoms or unexpected fit changes.
Also watch for obvious mechanical problems such as a rolled edge, a twisted seam, a closure that cannot align or a large gap in a place where the product is supposed to sit flat. Do not solve those issues automatically by choosing a smaller size.
The ASPS article on compression-garment care and skin checks emphasizes keeping garments clean and dry and visually inspecting the skin where the garment touches. If the back or another area is hard to see, it describes involving a support person to help check the skin.
Comparing a chart result with a product
After the surgeon has approved the category and coverage, shoppers can compare the chart with the exact specifications of a product such as Dr. Shape’s Stage 1 postoperative garment. The product page currently identifies its own stage, coverage and closure design. The link is an example for comparing specifications; it is not a statement that the product or size is appropriate for a particular patient.
Commercial disclosure: Dr. Shape sells the product and other garments linked in this article and may receive revenue from purchases. Product links are provided for shopping convenience and do not mean that a product is medically appropriate for a particular reader, procedure or recovery plan.
Before removing tags or wearing a garment for an extended period, review the return policy and perform only the fit check allowed by the seller. Do not alter, wash or wear the item beyond that policy if you may need to exchange it.
Information to have ready when requesting sizing help
For a retail sizing question, provide only what the exact product’s chart requests, along with the product name and stage. If the garment is intended for postoperative use, it may also help to know what the surgeon has approved regarding coverage and any layers worn beneath it.
Do not ask a retailer to diagnose swelling, select medical compression, interpret symptoms or replace the treating team. Retail staff can explain the store’s chart and physical product features; they cannot decide a postoperative prescription.
Frequently asked questions
Should I buy my normal clothing size?
Not unless the exact product chart specifically uses it. Dr. Shape’s current body-garment chart says not to use regular clothing size for the listed garments.
Should I use my pre-surgery weight?
Dr. Shape’s current chart directs shoppers to use current body weight for the listed body garments. A surgeon’s different postoperative instruction takes priority.
Should I size down for more compression?
No. Do not use a smaller size as a substitute for the correct compression specification or stage. Follow the exact chart and the surgeon’s written plan.
What if I am between two Dr. Shape body-garment sizes?
The current Dr. Shape chart directs shoppers between listed weight ranges to choose the larger listed body-garment size. If the treating physician provides different instructions, follow the physician.
Can weight alone determine every faja size?
No. It is the method used for specific Dr. Shape products listed on the current size page. Other products and brands may use different inputs.
What if the recommended size feels wrong?
Stop and reassess rather than automatically moving smaller. Check that the correct product chart was used, contact the retailer about construction and exchange options, and contact the treating team about postoperative fit or symptoms.
The practical sizing answer
Use the exact product’s current chart with honest, current information. For Dr. Shape body garments listed on the size page, that means current body weight; for its surgical bra, it means the separate band or underbust method. Other products may be different.
Never choose a smaller size simply to chase stronger compression. After surgery, written instructions about the exact garment, size, pressure, coverage, layers and schedule control every general retail rule.
