Fantastic! Vintage Orange Mushroom Disco Shirt from the 1970's. There are no tags on this so please go by my measurements. Features a pointy collar, button front, long sleeves with two buttons on each cuff. All measurements are taken with the garment in the relaxed position without any stretching. The fabric is more than likely a polyester, as it does have some stretch to it.
I would say this is a size M/L
18" across the back shoulders
22" sleeve length
40/42" bust
28" long
Vibrant Bold Orange Shrooms! Really cool shirt!
