There’s no shortage of summer dresses out there, but finding the ones that look effortlessly chic with minimal styling? That’s another story. We’re busy, we’re hot, and, frankly, sometimes we just don’t have the brain space to plan an outfit. That doesn’t mean we want to compromise on style, though.

We want to look fashionable, without trying too hard. Like we got ready in four minutes flat (because sometimes that's all we have) and walked out the door with a pristine ensemble and not a hair out of place. On those occasions, you need one piece that you can throw on, add sandals and sunglasses, and look instantly put together in minutes.

Well, we’ve scoured the high street to find the best summer dresses that do all the hard work for you. Think trending colours, timeless silhouettes and flattering fits that you'll reach for on repeat. No awkward cut-outs or fussy necklines – just easy, throw-on-and-go dresses you'll wear all season long. Better still? Every single one comes in at under £50.

Easy elegance meets laid-back style in this M&S denim maxi dress. With its drop waist, exaggerated ruched hip detailing, and pale green pistachio hue, it ticks plenty of trend boxes while packing in the versatile practicalities that denim possesses just for good measure, too. Oh, and did we mention it's made from 100% cotton?

Broderie anglaise is so timeless and pretty, but structured silhouettes and calf-skimming lengths can sometimes read a little stuffy. This ruffle-hem mini, crafted from 100% cotton, keeps the whimsy of eyelet embroidery fully in check. We love the addition of a tasselled rope belt for a subtle nod to the boho aesthetic.

Shades of yellow have been big news for a couple of summers now, and we're not mad those sunshine hues are sticking around. The structured bodice on this Nobody's Child design promises to flatter all body shapes and sizes. Plus, it's hard to argue with that sale price tag.

Similarly, brown is the fashion set's favourite neutral, and it's hard to question it decorating this pretty puff sleeve River Island number. Shirring works for busts big and small, while the A-line skirt will keep you cool when the next heatwave hits. Simply pair with sandals and a basket bag to perfectly finish the look.

It doesn't get any easier to wear than a linen shift dress. The gathered V-neck and short sleeves offer a new take on the classic style, while the minty green and white toothpaste stripes keep it feeling fresh in more ways than one.

Okay, we know what you're thinking – a knitted dress for summer? And in navy? But trust us, the open weave of this Mango midi allows for more than adequate ventilation as well as providing a smarter style for office days. A naturally heavier fabric, there is the risk it will just hang shapelessly from your shoulders, but the added belt detail will cinch you in at your narrowest point.

Contrary to common belief, bold patterns aren't tricky to wear. In fact, retro ‘70s floral prints – like on this Reserved design – are some of the easiest. Pair with a wooden clog or a platform sandal to really lean into the vibe.

T-shirt dresses are the epitome of effortless summer style, and a black style is inherently chic. Keep it casual in flip flops and a boat tote, or dress up the look with barely there kitten heels and a shoulder bag. Want to add a little more shape? Try a thick waist-cinching belt or a satin scarf tied around your waist.
