So excited about these - they're gorgeous!  Unless you have a big toe on either foot.  I ordered a "size 10" as is usual for me for dressier shoes, and while I can certainly get them on, they are uncomfortably tight in the toe box (width not length) as soon as I put them on.  In fact, on the left, my big toe made a little bump in the top of the shoe!  A different brand of ballet flat fits perfectly in a 10, so it's not just my feet!  Unfortunately, this is not available in an 11, or I would SO purchase it- adorable!
