"I spotted this H&M Lyocell-Blend Flounced Dress (£40) and thought the lemon print was adorable and the tiered ruffles was a unique silhouette for a high-street find. I didn't buy it, though, until weeks later when the temperatures were set to hit 39 degrees in London. Then, I realised that I had gotten rid of most of my old Summer dresses. Thankfully, they had one left in my size. The next day, not only did it help me stay cool (even on a particularly stuffy tube ride), but I also got tons of compliments — people couldn't believe I picked it up at H&M." — Sophia Panych, content director
