Kate Moss launches her Topshop fashion line at Barneys New York, dressed in a chiffon tunic by TopShop, on Tuesday night accompanied by TopShop head honcho Sir Philip Green.

The UK launch of her TopShop line earlier this month has been wildly successful. The collection goes on sale at Barneys today — let’s see if Americans gobble it up as much as the Brits!

Fellow Brit Lily Allen recently took a jab at Kate’s new clothing line, saying it’s only for “perfect people.” The outspoken British singer fumed to English magazine Grazia: “Kate’s clothes are just for skinny, perfect girls. I won’t be buying any. I couldn’t get into those tiny hotpants if I tried, and if I did I’d look ridiculous. The hard thing is to get everybody of every size to look fantastic. That’s the real deal. Fashion should be a laugh and be for everybody. My dresses will suit anyone, whether they’re tall or small, or fat or thin. The best thing about dresses is the fact they hide a lot of things you don’t want exposed and flatter the good bits. My bum and legs are revolting, which is why I wear dresses all the time. And I put in wider straps to hide the arm bits we all hate. I was really excited about doing my collection because I know what it’s like to feel uncomfortable in clothes. I don’t just chuck my wardrobe at someone. I got really involved with everything. I love my stuff - I’ve been wearing it loads.”

Kate Moss arrives back home after another night out in London with some more mysterious white powder stains on her black jeans on Wednesday. The Daily Mail reports:

“Having left London restaurant China Tang at 9.30pm, she didn’t arrive home until midnight - staggering out of the vehicle with specks of what looks like white powder down her jeans.

“Moss, who this week is celebrating the runaway success of her new Topshop range, had been dining with friends at China Tang restaurant in London’s Dorchester hotel.

“But what she got up to in the two-and-a-half hours between leaving Park Lane and arriving at her north London home remains a mystery.”

And customers were only allowed 20 minutes to get all of their shopping done!
