With heatwaves proving to be quite the regular occurrence this summer, it's no wonder so many of us are trying to adapt our wardrobes to suit the rising temperatures. After all, lounging on a beach in Ibiza wearing a bikini and sarong is a very different experience to melting in an office-appropriate 'fit on your commute to work.

If the above sounds familiar, then here's your solution. Butterfly sleeve dresses are the ideal way to stay cool this summer while keeping your arms covered (so you can kiss those sunburnt shoulders goodbye). Loose? Tick. Flowy? Tick.

But butterfly sleeve dresses aren't just functional for the hotter temperatures; they're so on trend right now and can be dressed up or down depending on where you're headed.

As for which butterfly sleeve dress is sitting in our basket right now? Marks and Spencer's Pure Cotton Tie Neck Midi Waisted Dress is effortless yet elegant, and feels lightweight even when you're on the verge of sweating it out on the bus to the pub. Beyond functionality, the tiered pleats and ruching elevate this otherwise simple dress, as does the open-front neckline, which can be tied up or left undone. Finished with an A-line silhouette, the dress is complimentary for all body types, too.

"This is a gorgeous dress. Easy to wear and suitable for anywhere and anytime," one five-star reviewer said of this M&S find. "Great to wear on these hot summer days and will be taking on holiday," someone else agreed, describing it as "flattering."
