Help with wedding/party dress

[MJOverInvestor]

I'd love all advice on this. I have a summer of weddings and big birthdays coming up. I'm size 16-18, in my 50s and usually live in black and grey. I look absolutely dreadful in florals but weirdly, a touch of metallic can suit me. I thought I'd found a dress (Bruuns Bazaar - I do love a Scandi brand) on Vinted that would have been perfect if (grrrr) it had actually been the size it was advertised (nb to sellers - size 38 is not 16-18). I've attached it. I've got a budget up up to £200 if needed. First wedding is mid-April and I'm starting to panic. Thank you!

Starting you off with a small selection from JL , the Jolie Moi is out of stock but worth registering in case it comes back in or looking at other stockists/Vinted. The Maya one busts the budget but is lovely

Here's one.

A few more…

Thank you so much… I forgot to say that o don’t love my upper arms much so sleeves are definitely preferable… so the Rosemary tiered dress is definitely on the right lines no will check it out… (if only navy blue wasn’t a school uniform colour - perhaps it’s finally time to work on that particular neurosis… 😂😂😂). VERY Grateful
