there's this pair of jimmy choo sandals on bergdorf that are my size 8.5B the thing is, it says there it runs small, which i find true with designer items. but today i went to my local dept store, we're a season slower so i tried on a 39 and they were a little too loose. the 38 was only a little too tight. they don't carry half sizes. so i mean...they are supposed to run smaller but the 39 was slipping a little on my right foot. i'm an 8.5 on my right but my left is more of an 8 that's why i always buy 8.5. in MJ i'm 39, miu miu 8.5, gucci 8.5, LV 39... what do u think about the jimmy choo sizings??? because i don't want to buy something that won't fit since i can't try it on and returning it would be VERY DIFFICULT... help me!!! thanks ladies!
