Vintage 1970s Three R's Women's Large 14 1/2 Abstract Funky Design Sheath Dress

Vintage 1970s Three R’s abstract design lightweight gauzy poly blend dress tagged plus size 14 1/2. Runs much smaller than modern sizing. 38” sth about 20” ptp (it goes straight into the angle of the sleeve so hard to pinpoint the exact bust) 19” across the waist. Has some stretch to it. Very lightweight and semisheer, so it needs a slip underneath. Has a couple pulls in the fabric near one sleeve and minor pilling.
