I'm a BM in SILs (H's sister) wedding this spring. She has been very indecisive about dresses partly bc she doesn't really know what she wants, but also bc one of the other BMs is pregnant now, but will have delivered about a month or so before the wedding. She's trying to be very sensitive to this BM. She finally chose a dress, but when she told us the price ($250 without tax, shipping (which I will need) or alterations) it's more than I had expected. So here's the problem, she never asked for a budget (but told us a dress that was $280 was WAY too much to ask us to pay) and this is too expensive.
H is pissed about this and wants to talk to her directly. I said I should do it because I'm in the WP. What's the right thing to do here? The dress is more than we can afford right now and I think she'll be really understanding, but who talks to her? I know the general sense is that "blood talks to blood", but that feels weird to me in this case. Thanks in advance.
