I love this dress! I am 58 and 175 lbs, with a 40D bust... I ordered a large in the red dress with lace collar, and it fits perfectly. The material is better quality that I expected. Its heavy and stretchy which is a plus! The dress is beautiful. I read through the reviews before ordering, and I am glad I did. This dress can be worn with or without a petticoat slip... it is beautiful with either, depending on the look you want.
