Leather belt with canvas trim

Item AY621, “Vegan leather belt with canvas trim”, is not a vegan item. The tag/label on the belt states “100% Cow Leather”. Embarrassing faux pas, J.Crew? Also of note for men’s belt buyers; my waist measures approximately 35” with a tailor’s measuring tape and I wear J.Crew men’s pants in waist size 31. The J.Crew size chart/info instructs to order belts a size up from ones pant waist size. This belt in size 34 was too large for me. I believe a size 32 would likely fit just fine, but still be made of bovine skin.
