Thanks both. I have a jumpsuit that isn't tailored like first two options but also is nothing like the third... When I wore it my friend said I looked glamorous, but not sure that's the same as elegant. My usual style is jeans, trainers and sweatshirts so not elegant!
I'm not a fan of lace, or very dark colours, as they don't suit me, which is quite limiting.
My alternative is a pale floral silk tea dress from Whistles which is nice but I wouldn't particularly describe as elegant... Are pastels elegant?!
I'd consider normal wedding guests outfits to fall into the category of 'elegant'. I don't think they're asking for anything out of the ordinary, they've just worded it a bit odd, so o wouldn't stress.
Someone wore a jumpsuit to my July wedding and for some reason I felt a little disappointed that she didn't dress up a bit more and wear a dress? Maybe I was being unreasonable. I got over it pretty quickly!
If your friend is a bit hip or trendy though, you can probably get a feel of what is appropriate or not for her summer wedding
I saw this on the Boden website the other day though and thought it looked very smart here
There will be more summery sleeveless dresses out soon though so you have time to find something if you're unsure.
I always feel like these dress codes are steered more at men and children rather than women, ie a strong hint for no trainers. Basically a nice dress or a jumpsuit and you'll be fine, I wouldn't read any more into it!
