Coast Saskia floral dress

This Summer's range from Coast owes a lot to Erdem when it comes to inspiration - think impressionist florals and painterly prints on chic little dresses - so if you fancy a bit of designer style at high street prices, don't forget the formalwear faves. They have a lot more to offer than just strapless satin frocks.

The Saskia dress has all the hallmarks of a wardrobe staple - soft jersey fabric, modest neckline, sleeves for warmth and coverage, and a tie detail on the waist that will draw attention to the right body parts. And it's reduced in the sale, down from £95 to just £45. If you're off to Ascot next week and you still haven't sorted your outfit, this might be the perfect last minute buy, or stash it away for those nightmare-to-dress-for Autumn weddings - you could easily add tights underneath.
