Bras & bralettes

Your first bra: shape, comfort and a size worth checking

A pretty bra can change how a blouse or dress looks. The useful starting point is the combination of your body, any breast forms you wear, and the exact bra—not a universal conversion from a men’s shirt size.

← All clothing guides

Start with your own shape.

  • Underbust: measure around your ribcage with the tape level and comfortably snug.
  • Bust: measure around the fullest part, wearing the forms you intend to use if applicable.
  • Record the units, then follow the chosen brand’s band-and-cup method.

Feel matters as much as fit.

  • Smooth cups can give a cleaner line under thin tops.
  • Lace brings a different texture; check whether its seams or pattern show through your outfit.
  • Stretch bralettes and structured bras create different shapes and support.

Decide what the bra needs to do

Consider whether you want a gentle everyday layer, support for breast forms, or a particular shape beneath a dress. If you use forms, check the maker’s fit guidance and whether the bra holds them securely; a pocketed bra may be appropriate.

Check band and cup together

Band numbers and cup letters work together, and sizing methods differ. A cup letter is not a fixed volume independent of the band. Use the brand’s own instructions rather than guessing from a single ribcage number.

Move before deciding

Check the band, cup edge and straps while sitting, lifting your arms and wearing the top you intend to pair with it. Underwire should not dig into tissue or forms; straps should not need to carry all the support.

Avoid the common shortcuts

Do not assume that every size with the same cup letter will fit identically, or that the prettiest photograph guarantees the shape you want. If you are between recommendations, compare the two styles’ details and the seller’s return rules before buying.
