My FI and I are having three flower girls who are all 5 years old (one niece on my side, two on his). We've been very casual about it and we're just going to see on the day of the wedding who wants to walk down the aisle and if one of them doesn't, no sweat, just go sit with Mom and Dad.
We found a $16 dress from H&M online that the parents were all good with purchasing and we told the moms that we'd give each girl a matching headband (along with their adorable jewelry box gifts). Then they could wear whatever shoes they want and if they want tights because it's cold, cool, whatever you want.
Meanwhile FMIL is freaking out about them needing sweaters because it might be cold (indoor wedding and we're not making the flower girls come with us for outdoor pictures). Okay, fine, if they're cold, I think their parents can handle bringing a sweater or jacket. But no, FMIL took it upon herself to go and purchase matching sweaters for all the girls. Alright, fine, that's okay, we don't care.
But THEN, she emailed my SIL (bro's wife) about the sweater and I don't know how she worded it, but my SIL was worried she was going to have to pay FMIL back and they are really tight on money this month. I don't think that was FMIL's intention, but her fretting is not helpful. And now she's been telling FI on the phone that she's worried about the flower girl's shoes not matching. I'm pretty sure my niece will be wearing the red sparkly boots she's currently obsessed with, and FI and I are totally fine with that!
It's a good thing we live 4+ hours away.
