Vintage Sunny Choi skirt suit w/rhinestone buttons size 14 Rizik Bros Washington

Vintage Sunny Choi skirt suit w/rhinestone buttons Size 14 (see measurements below) Purchased at Rizik Bros Washington Is it black or navy? It looks more navy to me (especially the lining), but I can't say I'm 100% positive. Shoulder pads in the jacket, small slit in the back of the skirt (see measurements) Skirt has elastic (just a bit for comfort) and a zipper in the back Acetate/polyester/rayon- not a lot of give, and a full lining that is not particularly stretchy Jacket measurements: Pit to pit 22" Shoulder seam to sleeve hem 23" Base of collar to hem (center back) 27" Shoulder seam to shoulder seam (across back) 17" Skirt measurements: Waist 32-33" Hip 45" Length 25" Slit length 6" Purchased at an estate auction; was hanging on a decrepit hanger with dried out foam padding- needs a cleaning. The pictures are part of my description. Please look carefully at the photos and ask questions as needed. Thanks!
