Size L navy blue maxi dress

Is true to size,my sister is a XL and it fit her pretty well but she isn't tall so it didn't look as good on her,this was brought for a friend but she didn't like it and it was to late to return it,it ha never been worn still in bag that it was sent it. Has a little lace in the back and Is floor length! Looks great I wish I could wear it :/
