Marks and Spencer's shirt-jacket hybrid set to be a must have for unpredictable summer weather come rain or shine

Marks and Spencer shoppers are ditching shirts and jackets in favour of a hybrid piece of clothing that encapsulates the best of both worlds, making it perfect for unpredictable summer weather. The £45 M&S Collection shirt-jacket hybrid, more commonly known as a 'shacket' is said to be ideal for those wanting outerwear when the rain is pouring, but don't want to overheat.

Crafted from pure cotton, the M&S Collection Denim Quilted Shacket can easily be thrown on over almost any summer dress, jumpsuit or trousers and top combo, and will keep you cool while being kind to skin.
