You call it a bed shirt; I will wear it out!
"The last set of FLAX pajamas (matching top and bottom) I purchased became my favorite travel outfit. I receive compliments in airports all the time. I also wear the jacket separately. And likewise, this nifty FLAX bed shirt. I can imagine wearing it to travel with tights. I love your fabrics and this plaid is especially fabulous! Thank you for guaranteed comfort no matter how I choose to wear it!"
