What it does: Normally you want your bra to be unobtrusive, but there are those moments when a gorgeous bra is just meant to be seen. For those occasions, it's smart to have a gorgeous, eye-catching bra, whether it's with sexy straps, beautiful lace, or a pattern that really pops.
When to wear it: Underneath sheer tops where the idea is that your bra is visible. Or depending on the venue, it can even be worn on its own as a bustier or bikini top.
When to replace it: This bra, even if inexpensive, can be seen as an investment and should ideally be one you can keep your whole lifetime, just as you do the clothes you wear on top of it.
