If you think that it's hard to find high-fashion items at an affordable price point, think again. Sometimes the best pieces at fast-fashion retailers like Forever 21 are disguised as wardrobe essentials—like the striped tank top that Lupita Nyong'o rocked on Monday. The way that she styled the staple proves that you don't have to spend a bunch of money to look like a million bucks.
Nyong'o showed us exactly how it's done by pairing her sleeveless blue-and-green striped crop top (shop a similar $11 look; forever21.com) with jade wide-leg trousers. You can grab a look-alike pair of pants from Forever 21's website too for only $23. The 34-year-old actress kept the color scheme going with blue sandals and green tortoiseshell sunglasses. A green Gucci Marmont bag added an extra touch of glam to the look, with its silver strap and matching GG logo. If you were thinking about splurging on the stylish crossbody bag, it's sadly not available for purchase online anymore. But you can steal Nyong'o's luxe look with similar styles here.
