No alterations. I am 5'10 fit floor length, I normally wear size 8/10 but this was a bit big on me so I would say it probably best fits a size 12. I also will sell/rent the sleeves I purchased separately for free, just let me know. Floor-length black lace maxi dress with textured floral embellishment, spaghetti straps, and an open lace-up back. Features sheer paneling throughout and a dramatic silhouette ideal for formal events, weddings, black-tie galas, and evening celebrations.
