Choosing the Right Bra for Your Bust
A complete guide to bra types, fabrics, and sizing — because most women are wearing the wrong size, and it's easier to fix than you think.
Finding a bra that actually fits starts with sizing, not style. Once you know your size, the rest is about matching fabric and construction to what your day requires — seamless for under fitted clothes, underwire or molded cups for extra lift, lace for a little romance.
Find Your Size: Shop Your Top
Rhonda Shear uses a simple approach: wear the same size you'd wear in a fitted top or blouse. If you're unsure, measure around the fullest part of your chest without a bra (or in a very light, unpadded one) and match it to the chart below.
| Size | Bust Measurement (inches) |
|---|---|
| XS | 30 – 33 |
| S | 34 – 36 |
| M | 36 – 38 |
| L | 38 – 40 |
| XL | 40.5 – 43 |
| 1X | 44 – 46 |
| 2X | 46.5 – 49.5 |
| 3X | 50 – 54 |
| 4X | 54.5 – 58 |
| 5X | 58.5 – 61.5 |

Bra Buying Questions
Warning signs include straps or wires digging in, breasts swimming in loose cups, cups overflowing, or the band riding up in back. A well-fitted bra should feel like a second skin — you shouldn't really notice it's there.
Instead of separate cup and band measurements, choose the same size you'd wear in a fitted top or blouse. If you're unsure, measure around the fullest part of your chest without a bra, or in a very light unpadded one, and match it to the size chart.
Both aim for a smooth line under clothing. Seamless bras are knit as one continuous piece with no stitched seams at all. T-shirt bras may have some seaming but use smooth, molded, or lightly padded cups designed specifically not to show through fitted tops.
