I've been lurking on the knot throughout my planning, but wanted to get your opinion on this because there doesn't seem to actually be much about groomswomen on here, just people giving it as an alternative to having your FSIL on your side. I am not close to FSIL, but I have one sister who is my MOH and FI has one brother who is his best man, so if we didn't put FSIL in the WP, she'd be the only sibling who wasn't, and we felt that would hurt her and maybe look bad to our guests.
So I asked her to be a groomswoman and now that we are shopping for attire, I seriously regret it. I want her to be comfortable and so I am encouraging her input, but FSIL absolutely hates groomswoman attire, it seems. Simple black shift dress with a silver or pink sash to match the groomsmen's suits and the wedding colors, black pantsuit with pink or silver blouse underneath, she doesn't seem to like any of the options I like. I have a feeling she's fishing to wear the BM dress (pink with silver accents), which wouldn't surprise me as she is a very feminine, girly person, but I don't want people to mistake her for a BM. She is a groomswoman.
Is there any solution other than letting her wear the BM dress or being draconian and prescribing what I want? Help appreciated from those who have actually gone the groomswoman route.
