In the grand scheme of things I'm sure this isn't actually a big deal, but I'd love some advice from you ladies if I should bother addressing this at all and if so, how to address it.
I have 6 BM, ranging from sister, childhood friends, college friends and FSIL. When I chose what they'd be wearing, I decided to keep it very open so that they could all wear something they'd feel beautiful in, only specifying 3 things: color (and since they'd likely be getting the dresses different places I said that a range of colors would be ok), length (I'm wearing a tea length dress, so didn't want them in anything longer than that), and for the dress to be a gauzy material (chiffon or similar.) They are choosing their dresses now, some of them checking with me for approval (not required!) and 2 of them have come back with lace dresses, which I'd really prefer they not choose, as it doesn't really fit the feel of the venue or anyone elses attire. Is this worth addressing with them, or should I not bother and just let them wear what they want? How should I talk to them about it if it's worth addressing?
