I am having a formal outdoor ceremony and reception in late October. My BM are wearing floor length lace dresses and I've asked my mother and FMIL to wear long dresses as well. Now, my FMIL's style of clothing is skin tight and very revealing. I am very concerned about what she is going to show up in. I realize she is a grown woman and can pick out her own clothes, but I don't want my fiance to be embarrassed and I don't want my wedding pictures to forever have her in an inappropriate dress. I don't know how to ask her nicely to send me a picture of an outfit before she buys it.
Also, my fiance's grandfather isn't one to go out of his way to dress up for any event. His idea of getting dressed up is going out to get a clean version of a shirt he already owns. And I understand that he can't afford a new suit, but, again, my attire is semi-formal. I feel like he would feel out of place the whole wedding if everyone is in cocktail attire and he is in jeans and a shirt. What is a good way to hint at the fact that I would like him to get a suit even it is from Goodwill?
