Please Be Sure To Look Through Photos For Approximate Measurements And Condition As We Do Not Accept Returns.  Photos Are Part Of The Description.   If you have an aversion to smells, such as perfumes, after shaves, smoke, or pet allergies ; generally our clothing and fabrics go through rigorous cleaning processes, and are stored in climate controlled facilities, but many items have been sourced from owners who have had them in their possession for sometimes decades, and I won\'t be able to guarantee them completely free of smells, or invalidate a history of pets, but, with a few exceptions, such as tagged items, leathers, delicates,  and so on, they will be cleaned.  We\'re very big on being kind to mother earth, we love the possibility of rehoming items with people who will appreciate them .
