Vintage - Two Cashmere Sweaters with Removable Fur Collar and Rhinestone Accents

A rare find! Two gorgeous vintage (circa late 1950s - early 60s) 2-ply cashmere shrug sweaters by de Loux--one cream, one black--with 1 genuine fur collar that snaps on to fit either sweater. These were my late mom's and are in excellent condition--no holes, pulls, or stains that I can see, and the liners for both (which are lace with a light mesh overlay for the body of the sweater) are intact with no tears or holes. They each feature crescent-shaped rhinestone closures in the front as well as two rhinestone round accents on the sleeves which pull up/pleat the sleeves slightly (see photo). All of the rhinestones are intact on each sweater and are in very good condition. As to the size, one of the sweaters has "38" on the tag and they are the same size as far as I can tell. They are too small for me (I wear size L) but my guess is they are on the smaller side of medium. They measure about 21" from back of next to hem, and sleeves measure about 16" from armpit to wrist. I'm not a fur expert so no guarantee, but I believe the collar is either mink or sable, it has a silky feel to it. (Note - Mom sewed her initials on the reverse side of the collar (see photo); you can either remove them using sharp embroidery scissors, or just leave them on as they don't show.)
