DEADSTOCK Vintage Mint Pansies Plus Sz Top 18

I'm still not sure if I can sell this, help me decide! This is a pristine, never worn, mint, jade, and hot pink stretch polyester shirt from Sears in the 1970s. Marked sz 18, a crazy rare plus size vintage find. It has 2 small belt loops on each side, but no belt until you add a new one. Measures 29" long and 20" across the bust unstretched, can stretch to 21.5". All beige mother of pearl buttons are in 100% untouched condition and no flaws whatsoever. Don't let this gem get away!
