The marroon-flowery shirt is a small,i think its polyester? The green/blue shirt is cotton, tag says medium but is actually pretty big, especially across the chest. The cocktail dress is a size 8,cost a small fortune but i never get a chance to wear it.Its very very comfortable. Combination nylon, and lycra, 3 layers to the sheer skirt. Im open to trade for the shirts, but would prefer to sell the dress.
