Where to shop for a maternity dress to wear to a wedding?

Jocelyn

It’s my brothers wedding in May and I am looking for a maternity dress to wear to his wedding but I am really struggling with where to shop!?

I would really prefer to try some dresses on rather than have to order / pay and potentially return.

Even if they are online only, does anyone have any good UK shop recommendations ??

Thanks so much in advance :)
