Is this against my religion ?

Would you ever do a thing which is against your religion ? I m a hindu and recently visited manali, rohtang and a lot of other places in india as a trip with my husband. It was hell cold there and i had to buy some accessories and stuff to protect frm cold. I saw a cool pair of black leather gloves in a shop and couldnt resist myself buying those. I purchased them and they looked cool. They were 100 % genuine leather with cashmere lining on the inside and they looked fantastic and stylish on my hands and they were warm too. I dont know whether they were meant for men or women , but i bought them as it was very chilly and i had to protect my hands from cold. But then i realized, that leather is made from cow skin and me being a hindu , the cow is a sacred animal for hindus. I kept on thinking about this on journey back to hotel where we were staying. I felt a little guilt inside as whether i should have bought them. Should i have bought gloves of some other material like wool or something. Have i done anything against my religion ? i am confused. The gloves are amazing and look cool and feel warm, but this feeling is something i cant get rid of. What you people think ?
