I'm small-chested and the padding on this is honestly perfect, just enough to fill things out without looking fake. The gold clasp in the back is a nice touch too, though the band doesn't adjust so I'd measure before ordering. Straps stayed put all day at the beach.

Finally a triangle top that doesn't gap on my A cups. The built-in padding is light but somehow makes everything look fuller without that fake push-up shape, and the straps actually stay where I adjust them.

I'm pretty flat-chested and most triangle tops just hang there, but the firm padding in this one actually gives me a little shape without looking fake. The gold clip clasp is a nice touch too, though the band doesn't adjust so definitely check your size.
