Your date night beauty routine (and accessorizing!) just got a whole lot easier thanks to Derek Lam and Estée Lauder creative makeup director Tom Pecheux, who collaborated on a sleek clutch filled with makeup essentials [2] perfect for a sexy night out.

The navy minaudière was inspired by Estée Lauder's iconic dark blue hue, which is sporty enough to work with jeans but elegant enough for cocktail dresses, as well. "I designed the clutch to be a chic yet very adaptable accessory in a woman's wardrobe," said Lam. "Every woman seeks that perfect small bag."

Inside, you'll find five must haves Pecheux created based on the fabrics, textures, and tones of Lam's Spring 2014 collection [3]. The lineup includes a navy and gold palette: Kajal Cray in Near Night, mascara in Black Black, eye shadow in Smoked Gold, lip color in Smoked Blush, and lip gloss in Barely Gold. "The products are subtle and wearable yet can also be used to build a strong, sexy look," explained Pecheux, who has been Lam's go-to guru backstage for seasons [4]. "It's the perfect mix for creating a sophisticated day look that can be turned into a sensual evening look."

The Estée Lauder Derek Lam Collection [5] ($85) is available now. We suggest keeping it in your desk, because you never know when you'll have a hot last-minute date.
