i ordered the pink brand flats (edie flats) and sized down as they recommended (i'm usually between 6.5 and 7, so i got a 6.5), and they were too small. i don't know if that's just me, though? i hadn't heard of that brand until recently but now i'm seeing their shoes all over.
are the shoes by Pink or Pink Studio? I know LTB has carried Pink Studio shoes in the past. I have these shoes by Pink Studio I'm usually a 6.5, sometimes a 6 and the 6 in this style fits me perfectly but they are also really soft and have a lot of give so I wonder if I would really need a 6.5 in other styles. Maybe based on the fact that my shoes just barely fit and kate's were too small when she sized down you should order your normal size. HTH a bit.
