I tried alot of this on at Target last night. Unlike most of the designer collections, the clothes actually fit like they were designed to fit.
The tuxedo jacket was very cute, and well fitted. The tuxedo shirt was made of super cheap almost sheer cotton, which I couldn't get over, but it fit ok. as did the tux pants, and bermuda shorts.
They only had 3 of the dress styles out last night, so I didn't try any of them on.
