I'm going to a wedding in Spain in May. I'm extremely celtic and don't cope with heat or sunshine at all, it's expected to be mid 20s C (which is too hot for me) and the wedding will be outdoors. The dress code is 'formal'. I am only a cousin of the bride, so not an important member of the bridal party, which I'm hoping means that I will be held to a lower sartorial standard.
I'm extremely apple-shaped and so need dresses that either have no waist or a high/empire waist as my bust size and waist size are so drastically different. Bust is size 16/18, waist is approx 22/24. I generally wear casual, flowy dresses in the summer in a size 18 but none of them are dressy enough for a wedding.
I quite like the look of this but would prefer cotton for coolness. https://chapter.london/products/yasmine-dress-red-black-paintstrokes?variant=44529923752222
I also really love this, but wonder if it would be formal enough. https://atlastshop.co.uk/products/coming-soon-cotton-annabel-maxi-dress-in-midnight-blue
I could also possibly make this dress (I would add sleeves) with a maxi skirt https://criswoodsews.com/products/parasol-dress-and-top in the fabric in the photo (which is more glorious than the photo makes it appear).
Any suggestions?
