I am not good about sewing clothes, so take my advice for what it's worth...you might take it in on the sides and/or hem it.
I didn't realize it was employee-appointed wear.
The owners would have problems paying extra for anything! It's terrible but we think the gym is being run into the ground and they've shifted any profits into a high end motorcycle business that's not doing well.
or just take the bottom front hem and pull it up and out of the collar. that's always a hot look.
or belt it and wear it as a shirt dress with nothing on underneath.
