This is the first maxi i purchased this summer. i went with a petite as the regular length would need to be altered and i didn't want to lose some of the pattern on the bottom. it is a beautiful flowy dress. no need for a slip. it has beads on the bodice. i kept the dress but it is tight at the chest area and sizing up wouldn't have made that much of a difference..kinda uncomfortable in the chest area. has yet to be worn so may return..
