Birkenstock and Tekla team up for their first collection dedicated to cozy, high-quality pieces for the home. The collaborative Pajama Shirt is cut in an oversized, slouchy fit for increased comfort and features a button closure with mother of pearl detailing. Crafted from 100% organic cotton that is free from harmful chemicals, the fine poplin weave offers a lightweight finish. Although it’s been made with sleep in mind, this is the kind of shirt you’ll want to wear everywhere.
