21 best summer dresses that are currently in stock (for now)
If you were to ask the GLAMOUR office what they're shopping for RN, every single one of us would say the best summer dresses. London (AKA the UK office's HQ) is stuffy on a cool summer's day, so throw a heatwave into the mix – where temperatures can reach a cosy 34°C – and everyone's sartorially stressed.
Fret not; a good summer dress will actually see you through from April 'til October, when it's time to dig out your knitwear all over again. They're the sort of frock that layers well – be it with a white t-shirt underneath or a trench coat over top – and that can be stripped back or styled up.
They're also the only silhouette you're guaranteed to see more than one of on every spring/summer runway, and, as per usual, there's a smorgasbord of shapes, lengths, colours and fabrics to choose from for 2025.
Gabriela Hearst, Miu Miu, Chanel and Chloé have been dictating which styles we pay particular attention to, with bright, patchwork patterns, high-neck and sleeveless silhouettes, and high-low hemlines and summer blacks being spotlighted.
What dresses are on trend this summer?
Aside from polka dot dresses, work dresses and the best wedding guest dresses (if you've got a few ceremonies to attend), everyone seems to be obsessed with drop waist dresses, smocked styles, and casual T-shirt dresses. Of course, GLAMOUR editors had to get a head-start and try a few new-in styles before everyone else, so the silhouettes you see us in below are ones we've been testing since April. Dedicated to the cause? That's us.
As for the materials to look out for when it comes to the perfect summer dress? Linens and lightweight, breathable cottons are a good place to start. You'll thank yourself for it on those stuffy/humid days where anything too clingy will make you feel claustrophobic. There's truly nothing worse.
Floaty frocks and maxi and midi styles will, of course, always remain a comfort blanket for most of us, and although a miniature hemline can be quite daunting, don't shy too far away from them – they're everywhere this summer and your legs will be grateful for the hit of vitamin D.
