This is an awesome vintage 60s swim coverup OR loungewear bed jacket made by Rose Marie Reid. Made of nylon tricot, the purple & blue MOD floral print is still vivid after all these years! 3/4 sleeve, hooded with tie at neck but otherwise open front, 3/4 sleeve with elastic wrists.
 
Pre-owned, used; in good condition with no noted flaws.
 
No size given on the label but it is small on my size 4 mannequin so I'm calling it an XS. The actual garment measurements are given next--
BACK pit to pit measurement-
22" Front is open
Center front length- 26"
Sleeve length- 19"
