This is a fun costume. People reviewing this costume on other sites say that there is a double layer skirt. However, that is not true with this costume and is kind of sheer. You will definitely have to wear something underneath &40;like a slip&41;. The cuff of sleeve where the red puffy sleeve ends and the blue longer sleeve begins is a bit snug considering that this is a plus size costume. My arms are not that large either. I wear size 14/16 and this costume basically fits true to size &40;^Comfortable,Easy To Put On,Fun To Wear,Stylish,Unique^
