Vintage 70's S white crochet lace covered button 1/4 sleeve hippie blouse top

Vintage 70s Trolly Car Small white cream crochet lace 1/4 half short sleeve boho hippie blouse top! So pretty. Subtle stripe pattern. Long side slits. Crochet lace all along hem and sleeve ends. Covered buttons up the neckline. There is yellowing under the armpits (see last photo). I've soaked it and now currently soaking it again but they are there. It's a batwing cut so I've worn it ok. Maybe someone has a trick to get them out? Was like this when I bought. Priced a bit lower. Happy to answer any questions ♡♡ Measurements: Pit to pit - 17 1/2 inches across. Length from shoulder to hem - 23 inches with the lace. 21 1/2 inches where lace starts.
