I ordered these shoes in taupe and they are really cute.  The taupe is actually more of a gunmetal color with black as well.  But, I think if you wore them with brown it wouldn't look bad.

The shoe is comfortable and true to size.  But, while the buckle adds great detail, it digs into the top of the foot a little.  I think once they break in a little, the top won't be as stiff and the buckle will flex a little more.

I usually find that flats don't look right on me since I have a bigger foot but these actually look good.  I think the big buckle helps balance out the shoe.  I'm thinking of ordering the brown as well.
