At belle SIMONE, we don't design for just one body. Your bra was never made with you in mind. This one is. The Signature Tank comes in sizes S–6XL, with real cups and wide straps designed to support every bust — no squeezing, no marks. Because comfort and dignity shouldn't come in one size.
Slips on over your head, no hooks or clasps. Instant comfort.
Real sewn-in cups support you from the front: zero underwire, zero band across your back.
A temperature-regulating fabric that wicks away moisture — ideal during hot flashes.
Try it at home, risk-free.
At our age, we've earned the right to feel good. Belle SIMONE makes tanks that support you without squeezing, so every morning starts without dread — and you feel like yourself, plain and simple.
Drag the slider to see the support in action: on the left, no support; on the right, with The Signature Tank. The same body — supported, smoothed, no underwire and nothing digging in.
The numbers speak for us.

I wasn't expecting much and… wow, this tank is unbelievably comfortable. I literally forgot I was wearing anything.
I should have bought several during the sale: this top really flatters your figure! With my shape, it's hard to find feminine cuts, but this is so flattering and creates beautiful lines.
The fabric is very soft and great quality. The fit is perfect!

I'm an E cup and I'd tried everything. This one actually holds, with no underwire poking me. I've ordered two more.
No more tight band or red marks at night. My back can finally breathe, and I forget I'm wearing it all day.
The comfort of a tank with the support of a bra. I got it in three colors and it's all I wear now.
The fabric is light and breathable — no more clammy feeling in the afternoon. Such a relief every day.
With my arthritis, clasps were a nightmare. This slips on over your head in three seconds. Such a joy.
No straps showing, no bulges. Under a light blouse, you can't see a thing.
I got the 4XL and it fits perfectly. It feels good to find a brand that thinks of us too.
