These wonderful tanks and tees are so soft and easy to wear! If your dog is at the high end of the chest size range, go up a size, especially if your baby has long fur. Tees are made of 6oz. heavyweight 100% cotton jersey with a ribbed collar. Tanks are made of a soft 100% cotton ribbed knit with a slightly tighter fit than the tee. Combine it with any of our denim for a FABULOUS look! Wear it under a denim harness for added style (and so you won't be naked when you take your harness off!). Wear it alone to just look COOL! Available in sizes to fit dogs with chests from 11-40". PLEASE NOTE: Because these wonderful tanks and tees are made-to-order, they cannot be returned or exchanged. PLEASE NOTE: Price goes up with size
