The shirt dress / shirtwaister is a fashion classic; easy to wear, timeless, flattering on most body shapes and one of those looks that comes back again and again. But drop the hemline to the ground, and suddenly it become a lot more dramatic and bold...and a lot more difficult to wear.

But we do love a challenge, and the current crop of floorlength shirtwaisters really push the boudaries of wearability when it comes to colour - white is the way to go if you want to copy celeb fans.

Evan Rachel Wood was one of the first to jump on the bandwagon last Summer at the The Ides Of March premiere at the Venice Film Festival. She chose to wear a super-dramatic Alessandra Rich button-down gown with lace detail on the bodice, a belted waist and rolled double cuffs.

Meryl Streep gave the dress its second celeb outing when she wore in onstage at The Revlon Concert For The Rainforest Fund earlier this month. She's obviously a huge fan of this style - she chose a similar black dress by the same designer for the Golden Globes too.

But it's not just Alessandra Rich who's putting her stamp on the shirtwaister - Leelee Sobieski recently showed us how to work the look in a killer creation from Jil Sander. She looked very Grace Kelly as she posed for photos at the 2012 Tribeca Film Festival Vanity Fair Party in a simple but fabulous dress.

But the question is, does this look have a place away from the red carpet? Will you be rocking a white shirtwaister any time soon, or is this one of many examples of high fashion that won't translate to real life?
