A couple of weeks ago we had a pajama day at work, and you bet I participated. We also had a breakfast buffet. Not a bad way to end my first week working there full-time.
I wore a Gap nightgown, Value Village cardigan, leggings, and Gap slippers. Strangely, I felt dressed almost exactly the same as I normally would, since dress/sweater/tights is a common uniform in my wardrobe.
The slippers and nightgown were a Christmas gift from Joe last year, normally my pajamas consist of old t-shirts and Old Navy bottoms. The Gap stuff is definitely a bit of an indulgence, and both items are comfy and well-made.
