DD Cup Bras

DD is one of the most common sizes women land on without ever being properly measured — it's the default "round up" size when a D cup starts to feel snug. Our DD range is built with wider bands and structured panels specifically for this proportion, not just relabelled D cup stock.

Sizing note

A DD cup means roughly a 5-inch difference between your bust and underbust measurement. If you've self-selected DD without measuring, it's genuinely worth checking — a surprising number of women are actually a cup size either side. Our bra fitting guide takes a few minutes.

Frequently asked questions

Why is DD often the wrong size?

It's frequently guessed rather than measured, since it sits just above the mainstream D cup ceiling. Measuring properly often reveals a different size either side.

What's the difference between D and DD here?

Roughly an extra inch of cup volume at the same band size — if a D cup gapes or a DD digs in, try D cup instead.
