I have a wide foot in a size 9 and ordered a size 9.5, a little tight in the toes but not where my foot would be considered wide due to the ball in the middle.
Absolutely gorgeous shoes, lots of compliments from the beauties in the office.
Pros
It was a bit tight, I used a shoe stretcher and they fit perfectly. Nice shoes.
Cons
The sash design may not be suitable for all formal occasions.
