Hello, I'm trying to decide if my 16 year old "little sister" too old to be a Jr Bridesmaid? She isn't my biological sister, she's a young girl as a family friend that has always looked up to me so I always considered her my little sister. I considered her being a Jr Bridesmaid because she's younger, she won't be able to attend the "EVENTS", & I do not expect her to help financially with any planned events. Jr Bridesmaid because she's younger or bridesmaid because she too old? She will have the same dress as the bridesmaid but it's more of a she's my little sister gesture I guess.
