My only knowledge of Dorothy Perkins was a black v-neck wool sweater that I took from my mom's closet many years ago. It's still a regularly rotated winter top in my wardrobe. I found myself browing their website and was really surprised at their great selection of flats! THEY ALSO SHIP TO THE US. HOORAAAH!!!!! The prices aren't crazy, though I do wish they'd post prices in $ as well.
These are my favorites, but the cobalt blue one in particular caught my eye. All these shoes are under £30, and the blue is on sale for £15.00!
