Bra Fitting Guide for Trans Women
Finding the right bra as a trans woman can be challenging. This guide addresses unique fitting considerations and helps you find comfortable, supportive bras.
Calculate Your Size
Measure snugly around your ribcage, just under where breast tissue begins
Measure around the fullest part of your bust, keeping tape parallel to the floor
Fitting Considerations for Trans Women
Broader Ribcage
Trans women typically have wider ribcages. This means you may need a larger band size relative to cup size than traditional calculators suggest.
Tip: Don't add 4" to your underbust measurement - use your actual measurement rounded to the nearest even number.
Wide-Set Breasts
Trans breasts tend to be positioned further apart on the chest, with more space between them.
Tip: Look for bras with a wider center gore (the part between the cups) or plunge styles.
Different Projection
Trans breasts often have less forward projection and a more conical or tubular shape, especially in earlier stages of HRT.
Tip: Shallow cup bras, bralettes, or sports bras often provide a better fit than push-up styles.
Ongoing Changes
Breast development on HRT continues for 2-5 years, with the most changes in the first 2 years.
Tip: Don't invest heavily in expensive bras early on - your size will change.
Recommended Bra Styles
Bralettes
Flexible sizing, comfortable for various breast shapes, no underwire pressure
Great for early transition or everyday comfort
Sports Bras
Supportive, accommodating for different shapes, comfortable compression
Daily wear, especially during early transition
Plunge Bras
Lower center gore works well for wide-set breasts
When you want more shape under clothes
Minimizer Bras
Distribute tissue across a wider area, work with shallow projection
For a smoother silhouette under clothes

Note: Note: This calculator provides estimates based on general patterns. Every body is unique, and the "right" bra is ultimately the one that feels comfortable to you. Don't be discouraged if you need to try several sizes or styles to find what works. The r/ABraThatFits subreddit has an active and supportive trans community that can provide additional guidance.
