Basel Open-Back Stretch-Knit Top

In contrast to REVOLVE, its louder, flashier sibling, REMAIN Birger Christensen is about those of-the-moment pieces you'll have on rotation for years. Since fashion isn't planning a breakup with sporty separates anytime soon – given how comfortable they are, we can all breathe a sigh of relief – the brand knits the Basel top from a stretchy ribbed fabric, adding a surprise flash of skin at the back. The best news? There's matching shorts to wear as a set.

• 63% viscose, 37% nylon

Remain excels in elevated, everyday essentials with a focus on high quality materials. Combining core classics with sportswear influences and playful elements, the resulting collections are relaxed, wearable, and quietly contemporary.
