Rihanna's the type of person who's not afraid to roll up her sleeves and get to work— if those sleeves are attached to an amazing, $750 windbreaker dress with a high-lo hem. That's what the singer-turned-designer showed up in when she made a suprise appearance at her Fenty x Puma pop-up shop in Los Angeles yesterday. Not only did she pose for selfies with fans, but she personally manned the cash register to ring up shoppers.

Lucky fans! If Rihanna swiped our credit card for a sneaker purchase, we would probably talk about it every day for years. There's still time for LA shoppers to check out the pop-up for Rihanna's Marie Antoinette-inspired collection for Puma, which ends its two-day run today. So hurry over there and cross your fingers that RiRi makes another visit to sell athleisure.

Even if can't visit in person, you can shop the Fenty x Puma collab online right now, including the very dress Rihanna wore to work the register.

Here she is in boss mode, learning how to ring up customers. You have to watch the video. Only Rihanna could make typing and scanning barcodes look so badass.

Because we need a full-length shot of her entire outfit.

Enough work, time to celebrate with champagne and selfies (click to see all the photos).

Rihanna cordially invites you via Instagram to visit her pop-up today!

Every salesperson should have a glass of bubbly, no?
