I've posted about asos.com before.  The options at that site are just plain awesome.  However, even with low shipping, ordering in the UK size was always intimidating...just intimidating enough to prevent me from actually checking out--regardless of how often I filled my cart with oh-so-cute items.  Well now I can rest easy (are you telling me shopping quandaries don't keep you up at night? [gasp]) because the trendy UK retailer has  made its way across the pond.  Not only can you see prices in dollars but sizes now reflect US sizes.  And the best part?  Free shipping!  What's not to love?
