This is THE quintessential "I have my life together" pajama shirt! The fabric feels super luxurious and actually makes me feel cute when I go to bed. I'm 5'6, 125 pounds and normally sway between small and medium shirts, so I went with a medium for a more relaxed fit!
The piping detail is sooo pretty. I've tried a lot of button downs and sometimes feel they are too tight around the armpit area -- this is nice and roomy and I don't feel constricted at all. Love to pair it with both the pants and shorts!
