Quick Answer

For the NILDA Top, choose your usual bra band size and adjust the halter tie to fine-tune the fit. Measure your underbust and bust to confirm, then use the adjustable neck tie to customize support and coverage.

Why the NILDA Top Fits Differently for Small Busts

The NILDA Top is designed specifically for small chests (IBTC), so its sizing differs from standard bikini tops. The triangular tankini-style bodice and UltraPush™ technology add shape without requiring a larger cup size, meaning your usual band size is a reliable starting point.

Because the top relies on a halter neck tie rather than a back clasp, the fit is highly adjustable. This is a plus for small busts, but it also means the tie placement and tightness significantly affect support and coverage—worth getting right for the best look.

Common Sizing Mistakes to Avoid

One common mistake is sizing up for more coverage. The NILDA's thick padding and ruching already add volume, so a larger size may cause gaps at the underarm or a loose band. Stick to your measured band size.

Another is overtightening the halter tie to boost cleavage. This can pull the fabric up and create gaps at the bottom. Instead, adjust the tie so the band sits parallel to the floor and the cups lie flat.

Step-by-Step Sizing Guide for the NILDA Top

  1. Measure Your Band Size: Wrap a measuring tape snugly around your ribcage, just under your bust. Ensure the tape is level and comfortable. Round to the nearest whole number. This is your band size, which corresponds to the NILDA Top's size options. Use a soft tape measure and breathe normally—don't pull too tight.
  2. Measure Your Bust: Wrap the tape around the fullest part of your bust, keeping it parallel to the floor. This measurement helps confirm your size, though for small busts the band size is the primary guide. If your bust measurement is borderline, choose the smaller band size for a snugger fit.
  3. Check the Size Chart: Compare your band and bust measurements to the LOU size chart. Since the NILDA Top is designed for small chests, your usual bra band size is the best match. If between sizes, opt for the smaller band for a secure fit. Don't size up for more coverage—the padding and ruching already provide shape.
  4. Adjust the Halter Tie: Put on the top and tie the halter neck so the band sits parallel to the floor and the cups lie flat against your chest. The tie allows you to customize lift and support. Adjust until there are no gaps and the ruching sits naturally. Avoid overtightening—this can cause gaps at the bottom of the cups.
  5. Test Movement and Comfort: Move around—raise your arms, bend, and twist. The top should stay in place without digging into your neck or slipping. If the band rides up, tighten the halter slightly; if it feels too tight, loosen it. The right fit feels secure but not restrictive; you shouldn't need constant readjustment.
