Is there a nice way to deter my 13-16 year old cousins from changing into tank tops and booty shorts for the reception? They always wear appropriate clothing for the ceremony, and then change into skin-tight tanktops and sweats/shorts. I know they want to be comfy to dance, but come on! Based on my invites and general tone of the wedding, it is set as a semi-formal event.
Please tell me this is something I won't notice, or care about. I just have looked back at the last five family weddings over the past 2 years and it irks me. I really want to have pictures with them at the reception (during the dance, etc), and I think it looks sloppy to have one person dressed formally and the other in gym clothes.
Could I ask them to stay in dresses? And to note, their parents dress appropriately, they just don't seem to care what the girls do at the reception.
