That is a really vile example of a jumpsuit. They can look very chic and stylish but they must be one colour only - strictly no prints. They must also be silk with a loose fit top half and a bum skimming trouser section rather than anything too baggy.
I don't like the floaty printed ones with harem pant bottoms. But the designer equivalent which is tailored and made of softer-yet-stiffer material do look good. Though they are perilously close to boiler-suit mechanic-chic which makes me wary of the whole idea!
I think they're hideous but keep looking at the cheap jersey boobtube/hareem pant ones and thinking the look sooooooooo comfy - have to keep having a stern word with myself as boob tube, hareem and jumpsuit are not words that should be allowed to describe a garment!!!!
i think you have to be tall, and slim of bum/tum. I am tall-ish (5 ft 9) with very long legs and thought i could get away with it (size 14) but have a bit of a tum and mine adds about two stone to me :-((
