A: Hello Deborah - Thank you for reaching out. A boy's slim size is for a tall, very thin young man. The waist is typically 2” smaller than a regular and the lengths are longer. A modern, trim fit pant has the same waist measurement as a regular but has a lower rise and a narrower seat and leg. Happy shopping! - Alicia

A: Hi Jjwy86 – Thanks for browsing our boot cut jeans! The primary difference between the two, is that straight leg jeans are straight right through, whereas the bottom is flared out in boot cut jeans. They will begin to taper at the knee, and there is a slight flare at the opening. I hope this helps. Thanks for dropping by. - Anita
