Not: Jessica Alba and bump

Grgeous Jessica Alba usually wins us over with her red carpet choices, but we were disappointed with this floaty Marchesa number which swamped her growing bump. She certainly looks as if she's expecting twins, as rumour has it... 

What kills it:
Bustier dresses look great on svelte ladies with small chests, but if you're pregnant they just weigh down the figure. Like the Grecian hair, though.
