My fiance's two little sisters (12 and 13) are going to be bridesmaids in our wedding. I want all of the bridesmaids to wear the same dress and we found a gorgeous dress that is age appropriate for my adult and teenage bridesmaids. The 12 year old is easily my tallest bridesmaid and will have no issue fitting in an adult dress, but the 13 year old is tiny, short and super skinny. Everyone says she should just get the smallest size and they'll be able to alter it, but I'm just super nervous about it. Has anyone been in this situation? Anyone had to have an adult dress altered for a junior bridesmaid? Were they able to do it? Any feedback would be greatly appreciated!
