1) Measure Yourself Correctly (Lingerie-Specific Measurements)
Lingerie fit is more sensitive than clothing fit. Accurate measurements make all the difference.
Measure snugly under bust. This determines your band size.
Measure fullest part of bust (not too tight). This helps determine cup size.
Natural waistline (where you crease). Important for high-waist briefs & shapewear.
Fullest part of hips/seat. Most important for panties, bodysuits, teddies.
3–4 inches below waist. Important for high-rise lingerie and shaping panels.
Over shoulder, through legs, and back up. Crucial for bodysuits/teddies.
Optional: helpful for long-sleeve bodysuits and robes.
Optional: helpful for thigh-highs and shaping shorts.
2) Bra Sizing Explained (Band + Cup)
🩷How Bra Sizing Works
Band size comes from your underbust measurement. Cup size comes from the difference between bust and underbust.
Different countries use different systems, but the fit logic is the same: supportive band + correct cup volume.
2A) Band Size Guide (Simple)
| Snug Underbust (in) | Suggested Band |
|---|---|
| 27-28 | 28 |
| 29-30 | 30 |
| 31-32 | 32 |
| 33-34 | 34 |
| 35-36 | 36 |
| 37-38 | 38 |
| 39-40 | 40 |
| 41-42 | 42 |
| 43-44 | 44 |
2B) Cup Size Guide (Difference)
| Bust - Underbust (in) | Cup |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
| 6 | DDD/F |
| 7 | G |
| 8 | H |
🔄Sister Sizes (When Your Band or Cup Feels Off)
If the band feels too tight, go up a band and down a cup: 34D → 36C.
If the band feels too loose, go down a band and up a cup: 34D → 32DD.
3) Panty Sizing (Every Cut & Rise)
| Size | US | UK | EU | Waist (in) | Hips (in) |
|---|---|---|---|---|---|
| XS | 0-2 | 4-6 | 32-34 | 24-26 | 34-36 |
| S | 4-6 | 8-10 | 36-38 | 26-28 | 36-38 |
| M | 8-10 | 12-14 | 40-42 | 28-30 | 38-40 |
| L | 12-14 | 16-18 | 44-46 | 30-33 | 40-43 |
| XL | 16-18 | 20-22 | 48-50 | 33-36 | 43-46 |
| XXL | 20-22 | 24-26 | 52-54 | 36-39 | 46-49 |
🧠Panty Fit Rules
- If it cuts into the leg opening: choose a style with wider leg elastic or size up.
- If it rolls down: rise is too low or waistband too tight—try higher rise or softer waist edge.
- If it rides up: coverage is too small or crotch width is too narrow—choose fuller coverage.
