The sleeveless jacket is the perfect cover up for summer - it adds another layer to your outfit and will do the trick when it starts to get a bit cold in the evening. It's also a chic addition to your outfit and is summer-appropriate; much better than taking a bulky jacket to wear over your summer dress or culotte-and-top-combo. The belt also means this can act as an outfit in itself. Wear over a slip dress to create a layered effect, with the different lengths making an interesting silhouette.
