Black authentic leather, cheap as possible needed for job interviews and to keep my jeans from fallin off my waist. I used to use a 32 waist belt but recently lost a lot of fat so now I'm at 30 waist. please help! Also not belt related, if I has nudie jeans that is size 31 and now is stretching too much since I guess I found out the hard way that I'm actually a size 30, what to do? Just use a belt? Buy a new pair? What to do?
