1990s UNIONBAY Shirt S (Fits oversized XS) Unisex

I assume it’s men’s w/ shrinkage (sleeves a bit short for men’s S) Off-white & Black While there are no holes & seams are intact, there are a few defects. Tortoise shell part of the top button is missing, & there’s mild staining on front (photo 7) and back (photo 8) right sleeve & a speck on front center (6, circled). Some serged threads were stitched over & are peeking out on right seam. Measurements (laid flat): - 24.5” Top Shoulder to Hem - 22.5” Chest - 20” Shoulder Seam to Sleeve End
