Nice fabric, buy a size larger than you need.
My husband is skinny. Skinny-skinny. He wears a 30 inch waist and has for the 30 years. Mr. skinny guy had a hard time buttoning the double closure waistline. However, I am a big fan of the double closure waist. It's superior to a button. It's flattering, and better made. These are slacks. He's an engineer and needs to wear slacks to work. I think they are professional looking and would look good on professional men. The fabric isn't the same as his 100 cotton Dockers, this is more of an upgrade from that look. My husband basically dresses like he could leave work and go hiking, but his job is professional, so I have to supply his wardrobe with a more polished look. These do the trick.
