The weather is hot, and the looks our favorite stars have been modeling this summer are even hotter! Wonderwall.com is taking a look back at the 30 best celebrity style moments of the season, starting with the ballerina-inspired tulle Giambattista Valli couture confection that Rihanna donned during the Los Angeles premiere of "Valerian and the City of a Thousand Planets" on July 17. The divisive dress, which featured an off-the-shoulder neckline and voluminous sleeves with an above-the-knee hemline in front and an epic train in back, certainly had fashion critics divided. But if you're like us, you appreciate a major outside-the-box fashion moment, and there's no doubt this was the biggest one of the summer! Now keep reading for more…

Cara Delevingne's fashion choices have been on point throughout the international press tour for "Valerian and the City of a Thousand Planets," but we were especially obsessed with the sheer silver Iris van Herpen dress she wore during the Los Angeles premiere on July 17. We just can't take our eyes off of the curve-hugging confection, which features a high collar and waves of wired detailing. It's practically a work of art!
That. CAPE. Celine Dion absolutely killed it in an all-white Ralph & Russo ensemble — a button-down blouse with slacks, a wide-brimmed hat, over-sized shades and a plain handbag — during an outing in Lyon, France, on July 11. But the true show-stopper was her cape, a cashmere floor-length creation embellished with ruffles and hand-embroidered cutouts. Divine!
There may have been a major sporting event taking place, but all eyes were on Pippa Middleton during the Wimbledon Tennis Championships in London on July 5.

Will Smith's missus wore a stunning canary-yellow Maison Rabih Kayrouz coat with a fringed hemline over a yellow Givenchy blouse and wide-leg Celine pants. Mellow in yellow? Anything but!
Olympic skier Lindsey Vonn rocked our favorite LBD of the summer during the ESPY Awards in Los Angeles on July 12. Her Monique Lhuillier minidress proved that sometimes more is more.

Zendaya let loose her inner Barbie girl in a beautiful hot-pink Ralph & Russo gown during the Los Angeles premiere of "Spider-Man: Homecoming" on June 28.

Second time's the charm! Duchess Kate was a vision in white in an Alexander McQueen coat-dress during the Last Post ceremony at the Commonwealth War Graves Commission Ypres Memorial in Ypres, Belgium, on July 30. She topped off her look, which she first debuted two years ago, with a feathered fascinator. (Only Kate can still top the best-dressed list in a recycled outfit!)
Major fashion faux pas? Nah! "Ingrid Goes West" co-stars Aubrey Plaza and Elizabeth Olsen intentionally coordinated in the same Marc Jacobs minidress during the premiere of the indie movie in Los Angeles on July 27.
