Nautical styles are still heavily associated with a fifties pin-up aesthetic, but if you're looking for a less severe take on the look this dress from Lover is a great choice. Taking inspiration from nautical fashion, this provides an easier to wear look that's still loaded with vintage style.
The Sailor-style dress is made from 100% cotton and features simple but effective elements of a sailor look. The monochrome palette allows details like stripes and the US navy style neckline and scarf to stand out, without looking over the top.
It's available online from Net-a-Porter for £330.
