Vests for morning if wedding

No idea if you can find a site which caters for both sizes, but if you can't, you could maybe buy them two plain matching vests and get them printed or buy "Bridesmaid" embellishments from eBay for them to iron on?

I want to do similar, I'm not going to spend loads as they will probably only wear it that morning. If you find anything let me know

This is what I'd do. You may find you can get vests that suit them both better if they're not from the same brand, but they can still match with the embellishments. It'll probably be cheaper too

These are mine that I've made. Vest tops matalan £3 and iron on diamanté from amazon £1.99. Hope this helps

These look brilliant - what a bargain!
