Meet The Keller Long Sleeve Jumpsuit in Black. This woven design is inspired by our best-selling Keller Wide Leg Pant and features relaxed trouser legs with a figure-defining bodice and long sleeves. It's handmade in Europe from a sustainable material that's infused with comfortable stretch. At the front, a zip fastening allows you to switch between a plunging V-neckline and a classic collared crew, depending on your style. Oh, and there's a hidden slant pockets at the hips, too.
Composition
Each Saint and Sofia style is made with premium materials that last. We’ve handpicked our production partners for their craft, attention to detail, and dedication to quality.
Comfort Obsessed
Our design team in London, England creates every style in our studios. We think about all of the little details before making samples in our own studios. These are endlessly tested to ensure the perfect fit and feel.
