Just like countless other 鈥90s and 鈥00s trends, pool slides have made a major comeback this summer. They鈥檙e not for simply tossing into your gym bag; a high-end slip-on style is the one designer item you need to have in your closet before the season ends. Don鈥檛 believe us? Check out the official numbers.

Lyst teamed up with Business of Fashion to analyze the top products of the season, filtering through a range of statistics using 4.5 million data points per hour from over 65 million annual consumers, four million products, and 12,000 brands. As for which specific style came out on top? That would be the comfy-chic throwback Gucci GG Blooms Supreme Slide Sandal ($290).

So why exactly are four of the 10 biggest fashion sellers of summer 2017 from Gucci? Marketing, of course! The young generations are loving the brand鈥檚 nostalgia-feel offerings. Yep, the 鈥90s are back, baby. Plus, according to Lyst and Business of Fashion鈥榮 findings, the new floral touch on their number-one slides were a genius touch for summer.

Gucci鈥檚 weren鈥檛 the only slides on the top products list, though. Givenchy鈥檚 Logo Slides ($295) came in at number five, in case florals aren鈥檛 your thing.

Low-top white sneakers also had their moment in the sun, with the Comme des Garcons ($125) and the Common Projects ($410) pairs clocking in at numbers six and nine respectively. Gucci鈥檚 Ace Embroidered Sneakers ($695) made the cut at number eight, while Saint Laurent鈥檚 Opyum Pump ($995) with the logo heel were the only high heels on the list, landing in the second spot.

But the summer of 鈥17 is all about accessorizing; Gucci鈥檚 GG Logo Belt ($420) scored third for hottest item and Chlo茅鈥檚 Nile Small Crossbody Bag ($1,550) came in fifth.

The last two spots went to the only clothes on the list, and they were both dresses. Not surprisingly, Gucci鈥檚 now-sold-out Pussy Bow Silk Cr锚pe de Chine Dress came in seventh. The last spot, number 10, went to the also sold-out DVF Serafina Dress. Check out the full list below!
