Vintage Made in Heaven Oversized Button Down Top

Great vintage condition, made in the USA, no flaws, lots of stretch, but I think might be sized incorrectly. Tag reads M, but it measures XL, my mannequin is Medium and fits her very large. See pics for measurements before purchasing. May be meant to be worn oversized. Reasonable offers welcome Tags: vintage 50s 60s 70s 80s 90s Y2K retro boho gypsy hippie fashion country western charm vogue style casual chic small business boutique reuse repurpose recycle
