Thanks everyone- the espadrilles I have are actually more obviously navy than the M&S ones (I bought them last year so the M&S ones were the closest I could find a link to). I do agree that they might not be formal enough though, I’ve got some tan leather heeled sandals that might work better.
I definitely won’t be in many formal photos. And I can keep the cardigan/blazer on in any group pictures.
I know the dress probably isn’t everyone’s taste (I don’t think many things are) but I’m open to other suggestions, especially from people who think it’s not formal enough or is too frumpy.
I’ve bought it to try on so it might look terrible anyway!
I’m mid thirties, 5’6 and a size 8-10 (small waist/boobs, bigger and bum, would ideally be able to wear a bra) if that helps influence what you’d suggest.
I’m perfectly happy to just blend in! It’s not my wedding so I don’t need to look amazing, just appropriate!
