I'm in the process of planning a wedding. I have asked our good friend's little girl (who will be four at the time of the wedding) to be our flower girl. I said (and meant it) that as far as I am concerned, she could show up in a Red Sox jersey and I would be thrilled - I just want her there for herself, not as a prop. The FG's mom said she would poke around and that she would be happy for an excuse to buy a fancier-than-usual dress for her daughter.
Recently the mom sent me a few dresses she'd found online for me to take a look and weigh in if one of them jumped out at me - they were all adorable, different patterns and colors, and I let her know the top couple that we liked, but reiterated that we just wanted her daughter there and she should wear whatever she likes best and/or whatever her parents like best or think she would wear again.
My question is, should I be offering to pay for the dress? I truly would be happy if she wore something already in her closet, and we have no "wedding colors" or anything else that the child needs to match, but I still feel badly that they are spending money on a dress that might end up being just for one event.
