Collarless Leather Jacket

Purchased this jacket approximately one year ago. I have worn it twice. Last week I went to grab it from my closet to wear it again and it had an awful chemical smell. I left it outside for a couple of hours to air out, but the smell is still very strong. It’s been almost a year so I obviously can’t return it, but what am I supposed to do? I’ve never had a real leather product smell like this.
