Changing bridesmaid dresses while reception.

Not all the attendants enjoy wearing the splendid attire goes through the whole wedding. Is it appropriate
to change the plus size
bridesmaid dress into a more comfortable one while reception?

Do you want to change outfits so you can
hang with your family at the reception and not feel bound to the bride's
entourage (instead of your brother's)? If it's okay with your brother and his
wife-to-be, then you're fine. But if not, respect their wishes and keep your prom
dress on. It's kind of fun to be in a cheap
bridesmaid dress at the reception -- pretend you're a princess at a swank
ballroom affair!

Insist on if you really feel uncomfortable,
this is your friends’ wedding, respect their ideas even though this is not your
fancy.
