Dear, NOTHING SPECIAL SHIRT

A dress shirt designed with deliberately nondescript detailing.
A removable collar keeper is attached to the back of the collar.
You can keep the collar straight by inserting a collar keeper.
It's not too compact and has just the right amount of looseness, so you can wear it on its own or as an inner layer under an outer garment.

The fabric is made of faux fur with a beautiful flowing pile.
It is knitted rather than woven, so it is stretchy.
The material is soft, supple, and feels pleasant to the touch without any itchiness.
