These shoes are cute, but they run very small.  I think Pleaser Shoes are progressively getting smaller.  I have a pair in size 9 that I've owned for a few years that still fit fine.  In nearly every other brand, I wear an 8.  I bought these in a 9 and they were still too small by at least a half size.  I should note that the size issue is the length of the shoe, not the width.

You'll definitely need to go up a size, maybe more.
