I Know Good Bras—These 23 Plunge Styles Are Game-Changing

Being a fashion editor, I’m usually the first person my friends come to with their style dilemmas, and right now, the question that keeps cropping up is, "Which bra would look good with this outfit?” With occasion season in full swing, many of us are now faced with working out which underwear (if any!) works with the outfit we have planned.
I’ve been quietly observing the trends coming through, and with lots of backless, strapless and plunging pieces on offer, there’s more emphasis on getting your underwear right than ever before. I myself spent inordinate amounts of time trying to find a backless bra to suit 1) the dress I had in mind and 2) my 32G cup size. It was an effort, but the reward of being comfortable enough to wear a dress style I previously never thought I’d be able to was so worth it. So today, I’m focused on helping you find your perfect plunge-bra solution.

Depending on your wants and needs, finding the best plunge bras can be tricky. My experience with them varies drastically—I have one I love and have bought in every colour it comes in (more about this style later). However, others have left me feeling unsupported and dealing with four-boob overspill. Not the look you want when you’re wearing a silk slip dress, let me tell you.
Identifying the needs of your plunge bra is crucial in choosing the correct one. Do you want it to smooth, to support, to look pretty or, the holy trinity, to do all three? Do you also need it to be strapless or backless? That presents another challenge. Fortunately for you, I love a challenge.
