Rihanna's unique style is evident in every outfit. For Rihanna, the founder of Fenty Hair, beauty is in the contrasts, from price point to aesthetic. And on a recent outing, Rihanna's playful style was on full display.

The musician and billionaire executive wore metallic Puma sweatpants, lime green and silver Puma sneakers, a graphic T-shirt by London-based independent designer Jawara Alleyne, a beige and brown Gucci large logoed tote, photographed in New York City. A quick calculation for comparison: the silver Puma T7 metallic men's track pants cost $130, the Ottlinger x Puma Mostro sneakers are $296, the T-shirt (now sold out) is £135, and the Ophidia GG Medium Tote is $1,750. Talk about contrasts.

Lili loves the high-low look. (The singer-turned-mogul recently paired a lime Bottega Veneta East West bag with $90 Puma sneakers; in May, she wore a see-through slip, a zip-up hoodie (hood up), and a $5,000 jumbo Chanel flap bag she wore.

Monochrome mania is another core part of the Rihanna style rulebook, from the streets to the red carpet. Last month, she went head-to-toe in crimson red for the red carpet at the Fenty Hair launch, styled by Jarryl Weaver. Last night's outfit, on the other hand, seamlessly blended the light heather gray of her T-shirt with the shiny metal tones of her bottoms, the silver stripes of her shoes, and her silver bracelet and necklace.
