Amazing Vintage 1970’s Navy Blue Horse Blouse

Coolest vintage 1970’s blouse ever. Long sleeved, with 6 inch slits at the bottom of blouse for comfort. Navy blue, with a pristine horse iron on at the bottom right. Ruffle clover with tie. 15 shoulder to shoulder. 17 at bust. 23 shoulder to hem. No size listed, but I’d guess a 10.
