DD is going to be a flower girl at DH's sister's wedding. DD will be one day off two years old. The dress is sleeveless. The wedding is at the beginning of January.
Dresses have been bought and there have been no plans to buy anything to cover them up with. Anything else will apparently ruin the look. (I get that, I've been a bride) But it will be freeeeeezing, DD is very little and there will be hanging round outside as there always is at weddings. So, AIBU to buy a matching-ish coat cardigan and put it on her when they are outside (or inside if it's cold)?
