Meet Fiona. Our newest family member, Fiona is the sleeveless cousin of your favorite laid-back Eileen. Fiona transitions seamlessly between all seasons. In the warmest months, wear Fiona to beat the heat and pair with a Tee Lab asymmetrical skirt for a date with your loved one. As the weather cools, let your shirttail peek out under a cozy sweater or fitted blazer without the extra bulk of sleeves.
