It’s quite thick jersey. I have a similar dress (different pattern - mine is light teal with birds on) but I never know what to wear it with. It’s not warm enough to go bare legs and sandals, I have short legs so trainers with it make me look frumpy. I end up wearing black leggings, which don’t quite look right, and Doc Martens, and a black cardigan which again is not the right colour. I like dresses - they’re more comfortable than trousers / jeans, with my mum tum - but I never know what to wear them with as I find tights itchy and uncomfortable, and never find the right shoes either!
