Uslu Airlines, an edgy cosmetics company from Berlin, offers a vast array of unusual fashion-forward nail polish colors. The five-free formula provides a durable glossy finish and I often find it lasting about a week with minimal chipping. Fun fact: each shade is named after an airport.
I'm obsessed with the NIM Niamey and WIC Wick shades from the main collection. NIM is a greyish green while WIC is a muted lilac. An alternative to NIM would be QBC Bella Coola from the USL collection, which would be very fun for spring and summer.
