Oh sorry I meant, get a size down!
I swear there was a thread about this a couple of weeks ago. search it.
My friend has that skirt, and it's proper stretchy, but a lot of their stuff is small, so you may as well get your normal size. It's not a very flattering skirt in person, btw.
Yeh that is an afwul skirt, there was a thread about it a few days ago. Bleurgh.
But as for AA their sizes are quite small, if the garment stretches.
edit: It actually says sometimes though on the website, that the garment will shrink the first time it's washed. So be careful.
It cool, but its E-V-E-R-Y-W-H-E-R-E
I have it in melange orange (had it in grey at one point but sold it to someone who wanted to look like Alexa Chung - no jokes) and I'm a 8, I bought XS. It is really stretchy too!
