We are having a small destination wedding on the beach in Key West. We've only invited family and are keeping it pretty casual. My future mother-in-law and sister-in-law don't have much money and so we are paying for their travel costs/accomodations/food so that they are able to attend the wedding. We have asked them to purchase their own dresses, but told them it just needs to be a casual sundress, nothing fancy. Maybe something they already own. My mom's dress is a teal, knee-length/scoop neck sleeveless sundress.
I just found out last night that they both purchased floor-length ball gowns (complete with crinoline, yikes!) from David's Bridal for the wedding. To make matters worse, my sister-in-law dress is off-white!!!
Once we found out, we tried to steer them away from those choices, telling them the dresses sounded too formal, saying we hoped they didn't spend too much money, concerns about the length due to the wedding being on the sand, etc.All pretty much fell on deaf ears... they way they look at it, their son/brother is only getting married once so they want to dress up for the occasion. In addition, they said they had purchased the dresses on layaway so if they changed their minds, they would lose the deposits they had left (I don't know anything about how layaway works).
I don't know what to do... the length and color particularly bother me, but i don't want to be a bridezilla. What they did completely goes against all the ettiquite rules i know, but i don't think they were being malicious... they just genuinely don't know. Should I just let it go? They probably don't ever get occasions to dress up so maybe i should just let them have fun. Should I be concerned that they are going to feel silly at our beach wedding in formal ball gowns when everyone else is wearing a sundress? Is it going to make my mom look silly in such a less formal dress in pictures? If I should say something, what do i say besides what I already said? Should i let my groom handle it?
HELP!!!!
