Triangle Bra – The Light Model Without Underwire

Short answer: A triangle bra is a light, wire-free model with triangular cups that gives a natural shape and minimal support. It is ideal for small and medium busts and for days when comfort matters more than lift.

What is a triangle bra?

The triangle bra is the simplest bra shape there is: two triangular fabric cups, thin straps and a stretchy band under the bust. No underwire, no thick foam cups and often no hooks. The result is a bra that weighs almost nothing and feels more like a soft top than a classic bra.

Who does it suit?

The model is best for small and medium busts, because the support is light and natural. If you need more hold, a firmer wire-free model may be better. See the full range of bamboo bras without underwire, and read our guide to bras without underwire if you are unsure which model to pick.

Soft everyday luxury in bamboo

In bamboo viscose the triangle bra becomes extra soft and breathable, so you can wear it from morning until bedtime without it bothering you. Pair it with bamboo briefs in the same soft quality, or see the rest of the bamboo underwear for women.

Frequently asked questions

Does a triangle bra give enough support?

For small and medium busts, yes. It gives light, natural support. If you have a larger bust or an active day ahead, a firmer wire-free model may be better.

Can you sleep in a triangle bra?

Yes, it is actually an obvious choice as a sleep bra, because it has no underwire, hooks or tight edges.

Can a triangle bra be seen under your clothes?

Its low, simple construction makes it almost invisible under most clothes, although the seams may show under very close-fitting, thin fabric.
