Bust: Great for any cup size. Fabric: Fabric is very stretchy. Length: Floor length. Size M measures approximately 60" from shoulder to hem. 5 STAR RATED DRESS! *Bought from LULU’s but never worn! Tag still on. I did have the length altered because it was very long- I am 5’4 and had on approximately 3” heels. So if you are my height or shorter the length will fit you much better than how it came. Or, if you are taller and wore flats that would also work fine. BEAUTIFUL dress: wish I was able to wear but ended up getting a different dress with more coverage due to colder weather. Bought for $79. Paid $80 for seamstress to shorten the dress. Listing price OBO!
