I think I have a thing for scuba. 100% polyester and fabulous. It never wrinkles, always stays structured and if you look on ASOS, comes in any number of hues at good prices.
This one was a bit of an impulse purchase. I loved the shape of it more than anything else: just above the knee, full in terms of volume and with cool box pleats. I knew it would be bright as it was classified as a neon but blimey....it's bright!
