Billie | Blue and Yellow Long Sleeve Top

A Light Top for Those In-Between Days

The morning feels cool, the afternoon turns warm, and you never quite know what to wear. You want something simple that adjusts with the day. A good long sleeve top solves it all. It is the sort of piece you will pull from the drawer without a second thought.

Billie is that kind of top. Light, classic, and easy to layer.

Billie is a long sleeve top with a timeless silhouette and a relaxed fit. It is cut to sit comfortably on its own or under another layer. The blue and yellow colors give it a cheerful, fresh feel that brightens the simplest outfit. It looks tidy on its own and quietly pretty under a cardigan.
