If you're after something floaty, feminine, and just really pretty, this £45, is a perfect pick. The midaxi length is ideal for events and more casual wear — not too long, not too short — and the angel sleeves add a lovely bit of movement.

It’s comfy too — lightweight and floaty, so you won’t feel restricted, and it moves beautifully when you walk. Great for garden parties, pub lunches or more formal events, just switch up your accessories to nail your brief.
