Don't size up.

I typically wear a 7.5-8, and I would have heeded STP's advice and ordered an 8, but at the time 7 was all that was available. Took a chance on the 7 and I'm very glad I did-- the fit is perfect and they're just adorable. Not quite as much arch support as the more heavy-duty sport sandals, but enough to keep my feet happy even during my current flare-up of sesamoiditis. I read a bajillion reviews all over the internet before ordering these, and had some concerns because several people mentioned rubbing where the back straps come together, but I've had no trouble at all. I wear the ankle strap just a bit loose, so that may be the key.
