The whole concept on an It Girl is over, and somebody should let Tamara Beckwith know. Her job is redundant, as is this grey velvet flared pantsuit. Can I just repeat that for everyone who may have thought I was making a funny:
Grey. Velvet. Flared. Pantsuit. As in, matching jacket and pants. As in a suit, made of velvet. I'm sorry Tamara, but the only woman who can get away with this is Kerrie Anne Kennerly (who I've seen pull it off brilliantly). I don't care if it's Louis Vuitton and you paid 5000 pounds for it. If you did, quite simply, you are an idiot. There's no nice way to put it to a girl who's choosing to dress like a man from the 1600's minus the pirate shirt.
The worst bit about the suit, the bit that if it wasn't there, you might have been able to get away with it if you wore nothing underneath instead of that high white shirt (which just makes me want to gag, violently), but the absolute worst bit is that trim, where the velvet has been sewn in a different way and so looks like ribboned edging along the suit. Good Lord woman! Are you an 80-year-old man who's reliving his youth while he pops down to the pub to perve at the young barmaids?
My advice is to go home, lock yourself in your wardrobe and don't come out until someone stylish (you must know someone in England who has style - and don't say Tara Palmer-Tompkinson, if she comes over you must keep quiet in the wardrobe until she's drunk all the liquor in your house and has passed out on the stairs) comes over and saves you from this rather dire style plight you seem to have found yourself in. This is all the advice I can give you from across the pond, the rest is up to you.
