Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Product Reviews

Rated 5 out of 5 by from Love this I have bought a couple of these shirts in different colors. They are a little bit small with sizing but I love the shirt. It is comfortable and light weight but keeps me warm. I love them for traveling- they are lightweight, comfortable, look nice, and don't smell!

Rated 3 out of 5 by from Low neck on cute top [This review was collected as part of a promotion.] Loved the color and the slim fit was flattering. However, the neckline was too low to wear with most bras. Sadly, I had to return it.

Rated 5 out of 5 by from The best thermals [This review was collected as part of a promotion.] Soft, warm and the perfect length and weight. I have bought them in multiple colours and will be wearing them everyday in winter.
