Vintage 50s Blouse with Zodiac Embroidery

Rare homemade vintage mint green blouse with Peter Pan collar, convertible closure, and a covered fly button placket featuring embroidered zodiac symbols (Taurus, Scorpio, and Sagittarius). I'm guessing this was made in the 1950s. Photos of the garment inside-out are meant to show the impeccable workmanship, regardless of being homemade, and a total lack of wear on the armpits - the most common issue I find with buying vintage clothing. There are no tags indicating size, but I'm assuming it'd be a large. Here are specific measurements - Bust: 42" Length from shoulder to hem: 23" Sleeve length: 7.5"
