This is a suit set-up from The Suit Company, made with REDA fabric. It's a navy blue color with a sheen and luster. The trousers have a non-slip waistband. The waist was extended to its limit at the store due to a change in body shape. I bought and wore it when I was 168cm tall and weighed 55-59kg, but I couldn't wear it anymore due to a change in body shape, so I had it dry cleaned and stored it in the closet. I've included photos of the tags, but I'll list the details here as well. No. HGT554 COL.
