One-and-done dresses are the staple that hold most of our spring/summer wardrobes together. No matter if your style MO leans minimalist or maximalist, once the weather starts to heat up, a spring dress or two take the guesswork out of building the perfect chic outfit, whether you're headed to the office, an alfresco brunch or jetting off to sunnier shores on holiday. Good news then, that the high street is crowded with many a great dress brand: Nobody's Child offers a dress for every taste, while Damson Madder has mastered the It-dress game, and then there's H&M, which delivers on all of the above and more.

No matter how many brands pop up on the high street, few are likely to boast a fan following of stylish insiders and fashion editors alike quite like H&M. From its highly coveted designer collaborations and premium Studio collection to the brand's classically affordable main collection, it has long been our de facto destination for everything from linen trousers and jeans to cosy knits and dresses.

As a self-proclaimed dress addict and fashion writer, I have access to an array of designer and under-the-radar gems, yet I find myself trawling through H&M's new-in section just about every week. Why? Well because, whether I need a clean-cut staple or a personality-infused sartorial statement, the brand's selection has it all. Not to mention, they're crafted with an attention to detail that often gets mistaken for designer, even to the well-trained eyes here at Grazia HQ.
The brand's latest releases are proof of its sartorial prowess: from ruffled chiffon confections and sequinned party-starters to souped up shift dresses and breathable linen midis, it's packed with just about every dress you'd need to get through summer in style. That said, with so many good options to choose from, how do you pick which ones make the final cut? Well, to save you hours of scrolling and decision paralysis, I've sifted through H&M's sizeable inventory and curated an edit of the best dresses on offer. Plus, many of the brand's bestselling pieces are currently on sale.

From lust-worthy collabs to trusty classics, shop the best H&M dresses below.
