You should order early. Most companies do not allow rush orders either. All flower girls gowns ordered in white or ivory, may now be returned for in store credit. Sorry, no cash refunds on children's attire and no returns on colored gowns. Mothers should order their gown 3-6 months prior to the date.
Moms gown takes just as long as a bridesmaid dress.
Many however can be rushed, but this usually comes with an extra charge. Absolutely no returns on mothers attire. Sorry, these gowns are ordered to your needs, and colors. Depending on the time of the year, tuxedos should be reserved 10-12 weeks prior to your wedding. If you are getting married during prom season like March through the end of May, you need to reserve your tuxedo in January and no later than the end of February.
