Push-Up & Underwire Bikinis
Structured tops for when you want lift rather than just cover. Padded cups, moulded shapes and underwire frames hold their form in and out of the water, so the shape stays the same when you stand up out of the pool.
This is the closest thing to a proper bra in swimwear, which makes it the shape most people move to if a triangle top feels too loose. Look for adjustable shoulder straps and a hook back if you want the fit dialled in.
