Karl Lagerfeld Paris Women's Black & White Striped Fabric Belt. 
There is no size tag but this fits me at an XL/1X. This is adjustable so it could work for smaller sizes as well.
Excellent condition.
Fabric portion of belt is 50" long. Allowing some room to buckle and drape, this should nicely fit up to a 40" waist.
Belt measures just under 1 3/4" wide.
Smoke free, pet free home.
