Quick answer

To get the best fit in the Rhea Bra, start by measuring your band and cup size using a soft tape, then use the adjustable straps and back closure to fine-tune the fit. The underwire should lie flat against your ribcage, and the silk-and-lace cups should hold your breast tissue without gaping or spillage.

Why the Rhea Bra’s materials matter for fit

The Rhea Bra combines a smooth black silk base with a sheer lace overlay. Silk has a natural give but does not stretch like elastic mesh, so the band size you choose must be snug without being tight. The lace overlay adds structure but also means the cup shape is less forgiving than a fully stretchy fabric. If you are between band sizes, opt for the larger band and use the hook-and-eye closure to tighten — this preserves the lace’s shape and prevents the underwire from digging in.

Common fit issues with underwire silk bras

Underwire bras like the Rhea Bra rely on the wire sitting in your inframammary fold (the crease under your breast). If the wire rests on breast tissue, the band is too small or the cup is too shallow. If the wire lifts away from your chest, the band is too large. Because silk and lace do not stretch much, these fit problems are more noticeable than in a padded or foam cup bra. Take the time to adjust the straps — they should carry about 10 percent of the support, not pull the bra up from the back.

Step-by-step Rhea Bra fitting process

  1. Measure your band size: Wrap a soft measuring tape snugly around your ribcage, directly under your bust. Keep the tape level and take the measurement on an exhale. Round to the nearest whole inch. If the number is even, add 4 inches; if odd, add 5 inches. This is your band size. Common mistake: pulling the tape too tight. The band should feel firm but not dig in — you should be able to slide two fingers under the band.
  2. Measure your bust for cup size: Stand straight and measure around the fullest part of your bust, keeping the tape level and not too tight. Subtract your band size from this number. Each inch of difference equals one cup size (1 inch = A, 2 inches = B, 3 inches = C, and so on). Checkpoint: if the difference is a half-inch, round up to the next cup size. The Rhea Bra’s lace cups fit better when slightly roomy than too small.
  3. Try on the Rhea Bra and adjust the straps: Put on the bra and fasten it on the loosest hook. Lean forward slightly and scoop all breast tissue into the cups. Adjust the straps so they sit comfortably on your shoulders without slipping or digging in. The center gore (the part between the cups) should lie flat against your sternum. Common mistake: straps that are too tight. If the back band rides up, tighten the straps — but if the band stays level and the straps still dig in, the band may be too large.
  4. Check the underwire position: The underwire should follow the natural crease under your breast and not poke into your armpit or breast tissue. Raise your arms — the bra should stay in place. If the wire lifts away from your chest, the band is too loose. If it presses into breast tissue, the cup is too small or the band is too tight. Checkpoint: the wire should never rest on breast tissue. If it does, try a larger cup size or a larger band with a tighter hook setting.
  5. Evaluate the cup fit: Stand upright and look for gaps or spillage. The silk and lace should lie smoothly against your breast without wrinkling at the top of the cup or bulging at the sides. If the lace wrinkles, the cup is too large. If your breast spills over the top or sides, the cup is too small. Common mistake: assuming a smaller cup will give more lift. A too-small cup actually flattens the bust and can cause discomfort. The Rhea Bra’s underwire and lace are designed for a natural shape, not compression.
