I really like the quality of their clothing. I have been in the Newbury Street store in Boston a few times, since they opened about five years ago, alas, not on the YLF expedition.
However I have also ordered from them online. If you meet the free ship requirements, i.e., buy a few pricey things, they ship free two day from the UK. And returns are free and prompt. No import duty.
I got quite a haul this spring: two of the diagonal sleeve blouses, a couple of dressy jersey tops, a striped sweater, a quilted jacket, and a flowered skirt. And then the temptress had to go and post the picture of the green silk front sweatshirt. Anyone wants to see a picture on a short person let me know. I am tempted by the suits, especially the Turkish blue, but I don't wear suits often enough any more to need another one when I have a very decent Theory suit for occasional summer needs. (I'm a lawyer but work from home and so dress for myself rather than conservative office or court appearances)
