I wouldn't do anything. Either they have the dress on the wedding day and they can stand as a bridesmaid, or they don't have the dress and they can sit as a guest. I don't have time to keep tabs on adults.
I think contact them and see why haven’t they order the dress yet. I didn’t have issue with mine because they bought their own dresses but with the guys I gave them all a different deadline than the actual deadline. It was like a week before to avoid the stress. I say call them and she’s what’s going on?
I would figure out why it hasn't been ordered yet. If it's a financial issue, that's one thing. If it's pure laziness, like Caytlyn said, they will end up being a guest. I wouldn't waist my time after that and if they get mad they were knocked off, then that's on them.
If they didn't have a bridesmaids dress on our wedding day, they wouldn't be in the wedding. Other than that, I let them figure it out. It's early to have a dress for an April 2020 wedding. A few of my girls ordered their dress 3 months before our wedding and they were fine.
It's still more than enough time to order a dress for an April 2020 wedding. They don't really need 6 months. I'm just saying this to try to relieve some of your stress. If the problem isn't financial, then you just need to tell them they need to order the dress, or they can come to the wedding as a guest--or not at all, if that's what you decide.
But I agree with Caytlyn, you don't really have time to chase after adults. If they can't handle it, they will miss out.
Well i would keep giving them gentle reminders and if they do it then great. if they don't - then i guess they are no longer a bridesmaid. You have more than enough things on your list to do for your big day. they should be able to order their dress on time. they knew this was a part of being in the party.
