Hi! I have never purchased either of these brands and actually I am new to couture shoes in general (I usually get aerosoles). I have somewhat wide feet and muscular calves (It is my build, I am a size 6). This affects my shoe selection because I look terrible in petite shoes or thin heels... Also, I have been a size 7.5 my whole life but the last 2 pairs of Aerosoles (which had straps) I had to go up to an 8... So with that said, I found 2 pairs of shoes I love but no returns are accepted as they are on sale. Can you tell me your opinions on the brands and the sizing? Should I order 7.5, 8, or should I just forget them? I hate to buy both and spend 300 and never use the shoes. Do you like one better than the other? Here they are Robert Clergerie Anna Sui Thanks for your help!
