I didn't buy my dress at Michelle's, only rented tuxes there, so I cannot speak for the dress buying experience at Michelle's.
DO NOT rent tuxes from them. DO NOT! If you think about renting them there and speak with someone named Monica, run! I live about 3 hours from Champaign but had my wedding in Champaign, and I spent a lot of (needless) time emailing back and forth with Monica. For some reason I had to repeat things over and over...she definitely was not really reading my emails or just has really bad reading comprehension because she would ask the same questions over and over....things I had already answered. When I talked to her on the phone she seemed very scatterbrained.
The day of the wedding all of the guys were wearing different styles of vests!!! They were all the correct color (black...kind of hard to mess that part up), but they were all different styles! Apparently after the long string of emails she still couldn't get it right.
My friend recently got married she also dealt with Monica and all the guys ended up with the wrong shoes - she had ordered them the wrong ones! She was told Michelle's would give her a refund for the shoes, but she hasn't seen it yet.
