Lollapalooza's official pop-up store, LollaShop, is set to open Friday, July 25 at Block Thirty Seven (108 State St.) in the Loop. Essentially, it's a space to sell festival t-shirts — but along with branded souvenirs, LollaShop offers some cool freebies and exclusive gear for the fest-obsessed.

New this year, a capsule collection commemorating the festival's 10th year in Grant Park has been created exclusively for Chicago. LollaShop collaborated with brands like BucketFeet, the Chicago Blackhawks and MADE Eyewear to create a “Lolla Loves Chicago” line of sunglasses, tees, sneakers and other accessories. Some of it is already available for pre-sale online, or shop the full collection at the pop-up starting Friday.

On the store's second floor, Red Door Spa has set up a salon and spa area to provide complimentary makeup refreshers, cooling oxygen blasts and a pony, braid and bun bar. Other options like mini-manicures, feather hair extensions and chair massages are available for $10-$20.

And next week, keep your eye on Facebook to find out about special appearances by Lolla artists and athletes who will stop by at various points throughout the weekend. Family of the Year, Hound Mouth, Ghost House and Glass Lux all came by for performances and signings at LollaShop last year.

LollaShop hours: Friday, July 25 9 a.m. to 4 p.m.; Monday, July 28 through Thursday, July 31 11 a.m. to 2 p.m.; Friday, August 1 through Sunday, August 3 10 a.m. to 4 p.m.
