Quick answer
Choose the Lydia bralette size closest to your underbust measurement and expect a close, comfortable band with full coverage from the silk-lined cups. The longline wireless design supports through band tension rather than underwires, so fit matters more than stretch.
Why the Lydia bralette fits differently from an underwire bra
The Lydia bralette is a longline wireless bra, so it relies on a wide band and stretch silk lining to hold the cups in place. That means the band, not the straps, should do most of the supporting. If you are used to tightening straps to lift an underwire bra, you will need to reverse that habit here.
The sheer navy tulle outer layer has less give than the silk lining, so the bralette may feel firmer across the cups than an unlined lace style. That firmness is normal and helps the neon embroidery hold its shape.
When to size up or stay with your usual size
If your underbust measurement falls between two sizes, size up for the Lydia bralette. The longline band covers more of your ribcage, and a band that is too tight will feel restrictive even before the cups come into play.
If you have a fuller bust, pay more attention to cup coverage than to the band number alone. The stretch silk lining offers full coverage, but the wireless design has less lift than a structured bra, so the fit should feel secure rather than compressed.
How to find your Lydia bralette size in five steps
- Measure your underbust: Wrap a soft tape measure snugly around your ribcage directly under your bust, keeping it level. Round to the nearest whole inch or centimeter and compare with the size chart. Measure while wearing a non-padded bra or no bra, not over clothing.
- Measure your full bust: Measure around the fullest part of your bust, usually at nipple level, without pulling the tape tight. The difference between this and your underbust helps you judge cup coverage. Keep the tape parallel to the floor; a dipping tape inflates the bust measurement.
- Check the band first: Try the bralette on and fasten it on the loosest hook. The band should sit flat against your ribcage and stay in place when you lift your arms. If it rides up at the back, the band is too loose. The band, not the straps, should provide most of the support.
- Assess cup coverage: Lean forward and check that the silk-lined cups contain your bust without gaping at the top or cutting in at the sides. The sheer tulle overlay should lie smooth, not pull across the embroidery. If the cups gape, try a smaller size; if they cut in, size up.
- Adjust the straps last: Set the straps so they stay in place without digging into your shoulders. They should be snug but not tight enough to lift the band off your ribcage. If you need to overtighten the straps to feel supported, the band size is wrong.
