Vtg Ken 1986 Twice as Nice reversible Striped Shirt + Red pants male doll Retro

Two pieces of male fashion doll clothes. The top is from 1986 set Twice As Nice by Mattel for Ken doll. It is striped knit on grey with yellow felty collar. Snap on back of neck. I have not IDed the red pants and do not know if they are genuine Ken fashions. They have two pockets which I put in the front but I suppose they could be back pockets as well. The elastic is stretched so it sits loose on hips. I would guess these are 1970s. Clothing only - doll is for modeling purposes only and is not included in sale. This is in preowned vintage used condition. May show signs of wear. Please see photos. Inv. F
