Use our step-by-step fit process to size the Minx T-Shirt Bra for smooth coverage under clothes, with checkpoints for band, cups, and common mistakes.
Quick answer
Start with your underbust measurement for the band, then use your bust measurement to choose a cup within the Minx T-Shirt Bra's full-coverage DD+ range. Always check the band first, because a loose band lets the cups gap and ruins the smooth look under clothes.
Why the Minx T-Shirt Bra needs a different fit check
The Minx T-Shirt Bra is designed with full coverage stretch foam cups and a wide back, so it behaves differently from a thin seamless bra. The foam cup holds its shape, and the wide frame distributes pressure across your back. That means a band that feels slightly firm at first is often correct, while a band that rides up will make the smooth cups wrinkle under a shirt.
Because the cups are full coverage and sized up to DD+, the fit checkpoint is not just cup volume but cup height. If the top edge of the cup cuts into soft tissue, the bra will show a line under a fitted top even if the band is right.
When to remeasure instead of adjusting
If you are between two band sizes, choose the larger band only when the smaller band leaves red marks that last more than an hour. Otherwise, stay with the smaller band and adjust the cups. For the Minx, the wide back and frame mean the band should not dig in even when it is snug.
Do not size up in the band to fix cup spillage. Spillage at the top of a full-coverage cup usually means the cup is too small, not the band. Remeasure your bust before changing band size.
Step-by-step Minx T-Shirt Bra fit check
- Measure your underbust for the band: Wrap a soft tape snugly around your ribcage, directly under your bust, and exhale before reading the number. Round to the nearest whole inch. This is your starting band size. Common mistake: measuring over a bra or clothing, which adds bulk and gives a band that is too loose. Write the number down; you will compare it with the band feel in step 3.
- Measure your bust for the cup: Measure around the fullest part of your bust, keeping the tape parallel to the floor. Subtract your underbust measurement from your bust measurement. Each inch of difference typically equals one cup size. Common mistake: letting the tape dip at the back, which understates the bust and gives a cup that is too small. If the difference lands between two cup sizes, start with the larger cup in the Minx because the full-coverage foam cup runs structured.
- Fasten the band on the loosest hook and check the ride-up: Put the bra on and fasten the loosest hook. Raise your arms overhead and lower them. The band should stay level in back and not slide up toward your shoulder blades. Common mistake: fastening on the tightest hook right away, which hides a band that is too large. If the band rides up, go down one band size and up one cup size (for example, 36DD to 34DDD or the equivalent).
- Scoop and smooth the cups: Lean forward slightly and use your hand to scoop breast tissue from under the arm into the cup, then smooth the top edge. The full-coverage cup should contain all tissue without cutting in. Common mistake: skipping the scoop, which leaves tissue outside the cup and creates a bulge under the arm. If tissue spills over the top edge after scooping, the cup is too small; try one cup size up.
- Check the smooth cup under a fitted shirt: Put on a close-fitting T-shirt or thin knit and look in a mirror from the front and side. The stretch foam cup should lie flat with no wrinkles or visible ridge at the neckline. Common mistake: judging smoothness under a loose shirt, which hides cup gaps and band issues. If you see wrinkles at the cup bottom, the band is too loose; if you see a ridge at the top, the cup is too tall or too small.
- Test movement and adjust straps last: Reach forward, twist, and sit down. The band should stay put and the center front should lie flat against your sternum. Adjust straps only enough to keep the cups in place, not to lift the band. Common mistake: over-tightening straps to compensate for a loose band, which causes shoulder pain and back ride-up. If the center front lifts away when you move, the band is too large or the cup is too small.
Product facts
- Minx T-Shirt Bra: Full coverage stretch foam cups up to DD+ size. The foam cup keeps a smooth shape under clothes, so the band must hold it flat against your ribcage.
Minx T-Shirt Bra - Minx T-Shirt Bra: Wide backs and frame with signature lace. A wide back spreads pressure, so a snug band should feel secure rather than tight.
