Super cute very practical sandal -- IF it fits you, and that's a big if, as it doesn't come in half sizes and the straps are not adjustable.

I ordered this sandal from the Chacos website in brown an 8 and it's just a bit too big everywhere.  But I don't think a 7 would do it.  I really need a 7.5.  An 8 been fine in the hiking sandal versions of Chacos, but only because I can tighten the adjustable straps down around the back half of my foot to keep my narrow heel from sliding around.  Since I can't adjust the straps on this one, back it goes.

This sandal has excellent arch support, the leather is sturdy but not stiff, and the heel cup didn't dig in to my ankle.  It's seems like it's a good walking around the city sandal and would go well with casual dresses.
