34G Bras Built for Full-Bust Support
34G calls for a bra that can properly support significant cup volume while keeping the band comfortable and secure. Wacoal's 34G collection of bras are designed with features like reinforced underwire, deeper cups, and wider bands that work together to distribute weight evenly, so the bra does the work instead of your shoulders and back.
Our range spans from smooth, seamless everyday styles to strapless options built to hold up under a dress or blouse. Whichever style you choose, every 34G bra here is designed to handle the specific proportions of this size without gaping, shifting, or losing shape by the end of the day.
Our popular 34G styles include:
Awareness Underwire Bra: A best-selling seamless underwire style with two-ply cups and a hidden sling for support, available up to an I cup.
Inside Job™ Wire Free Bra: A wireless style that still delivers substantial support, with a hidden sling in the cups for side coverage, available up to an H cup.
Red Carpet™ Strapless Underwire Bra: A best-selling strapless with medical-grade silicone strips and reinforced construction for secure, all-day support, available up to an I cup.

Frequently Asked Questions About 34G Bras
Is a 34G the same as a 32GG or 36F?
Not exactly, though they're close "sister sizes." Moving up a band size while keeping the same overall volume typically means going down a cup letter, so a 32G, 34F, and 36FF are closer in actual cup volume than the letters suggest. If a 34G runs a little large or small, trying a neighboring sister size in the band you prefer can help you dial in the fit.
Why do the cups gape at the top even though the band fits?
Top-of-cup gaping at a G cup usually means the cup shape is too shallow or too wide for your breast projection, not that the size is wrong. Look for styles with a deeper, more contoured cup or a plunge shape that follows your natural tissue more closely rather than sizing down the band.
How do I know if my 34G bra fits correctly?
Look for cups that fully contain your bust without gaping at the top or spilling at the sides, a band that sits level and doesn't ride up in the back, and straps that stay put without digging in.
