With its 15th edition running April 11-13 and April 18-20, the Coachella Valley Music and Arts Festival in Southern California is a bigger draw than ever—and not just for attendees but also fashion brands.

The event, which will feature such acts as OutKast, Pharrell Williams, Arcade Fire and Beck this year, counts fast-fashion retailer H&M as one of its nine main sponsors, along with beauty retailer Sephora.

Other style-driven names getting in on the Coachella action include Lacoste, which returns to host a pool party at a still undisclosed site April 12-13 from 1 to 6 p.m. Also on hand and sponsoring special events will be Guess. In addition, Dickies and surf and skate retail chain Tilly’s will co-host a “Desert Lounge” pool party at the Ace Hotel in Palm Springs the night of April 10 and all day April 11. The event will be open to fans who RSVP’d on the Tilly’s website.

Finally, Rebecca Minkoff’s online store is currently running a trend report and accompanying shopping area called “Festival Style” that shows girls the most Coachella-appropriate looks from the brand.
