When investing in the best summer dresses this season, cotton fabrics are the best place to start as the natural fibre is lightweight and breathable, allowing optimal airflow to the skin. This helps to regulate temperature in even the stickiest of climes.

A win-win, there are plenty of cotton dresses that, as well as being practical in the heat, are also super stylish. Lorraine’s dress is a great example of that, and her versatile shirt-style dress can transition effortlessly from day to evening wear and from casual to office-ready attire, making it and similar styles a great addition to your summer casual wardrobe.

No matter if you go for a striped shirt dress like Lorraine's or a more casual, A-line style, try styling it with a pair of your most comfortable sandals or some of the best white trainers for a casual everyday look. Or dress it up with some wedges, espadrilles or white court shoes for brunches or family gatherings.
