Maternity dresses for wedding guest?! (Plus size)

EJE • 👨‍👩‍👦‍👦👼🏼🌈🇬🇧

Any suggestions of where to buy??

I'm struggling to find pretty midi/maxi maternity dresses above a size 14! 🙄

I'm already not feeling great about myself and have a family wedding to go to in September where I'll be about 7 months pregnant. Don't want to spend a fortune but at this rate I'm willing to spend a bit more to feel good!

Thanks in advance 😊
