We thought the suspender belt trend was enough... Now bras are making the under-to-outerwear transition too!

Nope, it's not a wardrobe malfunction! With super deep plunging necklines, bras are out on show and worn with pride, not just as underwear, but as an actual part of your outfit.

Maybe not all of us are comfortable with having our lingerie on display, but thanks to Prada some of the most stylish of celebs have given this new look a road-test.

Let's take a look at the evidence...

The ever-daring Chloe Sevigny contradicted herself a bit, wearing her taupe bra on show with a cardigan. But she wasn't the only controversial one...

Pirates of the Caribbean star Zoe Saldana wore a dusty pink bra on show with a sheer turquoise blouse and burgundy skirt.

Brrrrr, girls, didn't you know it's winter? We'd rather put on a warm jumper and a scarf! But hey, Prada says this is in fashion, so what do you girls think?

Exposed bras: trend or tragic? Comments please!
