00’s suit styled Le Chateau bustier tube top

Made in Canada, 00's Le Chateau. Navy blue, striped XXS tube top/bustier with a sweetheart neckline that looks like a suit/vest. Side zipper and hook/eye closure. Loved this but doesn't fit and I rarely wore it. Freshly washed and a little wrinkly because of that, can be pressed. Thin, not boned, has rubbery stay up material on the inside upper back.
