So my oldest sister is getting married in September and my second oldest sister is the maid of honour and her best friend and I are her bridesmaids. She can only have three bridesmaids in the wedding and she is having her future niece as the flower girl. My younger sister is 13 and would be old enough to be a Jr BM but the wedding party is full already. My oldest sister really wants to be able to include my younger sister but we aren't sure what she could do.
Any suggestions?
