I'm getting married in less than two months, and well, I saw my fiance's mother's dress last night... OMG TOO DRESSY!! It's gorgeous- but its a one shoulder, full length dress with a little poof (very plain otherwise, but has rouching at the sides)... I'd wear it to a prom... or a ball.
First off, my mom is wearing a silk pantsuit. I don't know exactly what it's like- because she wants to surprise me, but I know it's not that dressy. It's formal, but not comparable to a ball gown. My bridesmaids have tea-length dresses, and my matron of honor's is short- cocktail length...and his mother knows this!!
I also told her about my mom's outfit-- all before she bought her dress. I'd say her dress may be even comparable to mine in formality.
This is probably stupid, but number one- I was so taken aback I couldn't even think to be like um no. Number two- she was really excited and I frankly didn't have the heart to be like 'wow. inappropriate.' Number three- I don't feel comfortable being like 'no, you can't wear that.' or 'No, you shouldn't wear that.'
I tried to drop hints to my fiance.... he was like 'who cares what anyone wears??'
(OMG it's inappropriate number one, number two if you want my family for the next 30 years to be talking about how uppity your family is, then fine.) So I explained how it's inappropriate for a guest- particularly the mother of the bride or groom to be more formal than the bridal party... and he's like 'well, I told you, we're Latino. They like to show off and get super dressy.' and I'm like- well that's still inappropriate. And not to snub your culture, but going dressier than the bridal party is rude and disrespectful.
He did finally then say he'd mention it to her- but I wasn't supposed to tell anyone she showed me. So I don't want it to be like I ran back and tattled and had a fit (which I totally did do- minus the fit). I'm hoping he'll just be like 'what are you wearing?' and she'll tell him, or if she doesn't, he says 'ok, just don't be too formal...' or something along those lines... but A) what if he doesn't?

what if she doesn't get it or listen??
I feel like the solution to this really is me going and being like 'I thought about it, and I looked at the girls dresses again, and their's are a little more casual, and not quite as formal as yours, so maybe it's not a good idea...' but I'm a big sissy and really really don't want to do that... I don't feel comfortable enough to do that, which is probably wrong, but that's where I'm at right now, especially since when her other son got married, she and her daughter-in-law were constantly butting heads, and there's no relationship there now.
So, suggestions??
PS-- she also had seen my sister's wedding album. My sister's wedding was much more formal than mine, and my mom wore a dressy pantsuit to that too (it's in all the photos)... why would she assume my mother would be dressier at my less-formal wedding than my sister's? I'd like to chalk it up to his mom being excited, but I don't know.. common sense please.
