Vintage beautiful lightweight floral suit jacket 2XL

It appears smaller than 2XL, please ask for measurements if you need to make sure on the size. Beautiful floral design, super lightweight being 100% polyester, an overall classic look… the black flaps give me Japanese kimono vibes. It’s in perfect condition except one loose button (see last pic), still hanging on however and I’m sure a quick sew job would get it back to 100%.
