love pieces like this with a story and sentimental value. I’ve gotten rid of things before like this and only regretted it.
First thought was to lean into the 80’s and think about shows like Absolutely Fabulous or Golden Girls. Pair with bigger pants, a low heel, and lots of jewelry. Colorwise, think you have to go white/black and let the jacket be the focus, or the opposite and just maximize color so the black collar isn’t so dominant. Wear it open with a more revealing/lace top.
for more casual, think punk. Your mini skirt and tights sound amazing with black boots, band tshirt/top underneath and silver jewelry.
