Blake Lively has reminded us why we rarely wear satin or silk. Even the most expensive dress - in this case a pale silver and blush number from Chanel's Autumn / Winter 2012 Couture collection- is no match for the back seat of a towncar.

Unless you plan to be standing from the moment you put the dress on, you can guarantee your gorgeous look will be ruined the moment the first crease starts to take hold. You can see Blake posing with her hands in the pockets to pull the dress taut try and conceal the creases across the front as best she can (or maybe she was just trying to hide her wedding ring?) but even that doesn't hide the lines across the hips.

It's a shame, because the unusual dress is beautiful. The layered straps and plunge neckline draw attention to that famous décolletage, but the length stops the look being overtly sexy (something that's pretty difficult when you're Blake Lively) and gives a bit of innocent prettiness to the final look. Pleats in contrasting colours on the sides peek out, giving the look volume.

Blake teamed the look with metallic round-toe Louboutins, a wavy blow-dry and pink lips.

Here's how it looked on the catwalk, freshly steamed!
