Skirting the boundary between romantic and minimal, Amy Lynn is the new London brand on our radar – and now yours, too. For all your formal summer needs (they don't call it wedding season for nothing) there's the Jolie dress. Crafted from fluid satin that languidly drapes over your frame, it's fitted at the waist with a self-tie belt, while the deep plunging neckline brings the va-va-voom. Slip it on with your favourite strappy sandals, we say.
