I recently bought some pants at Old Navy that I loved. They were on super clearance--I paid $4 (the original price was $42!) and they fit so great except for that waistband! I bought them anyway, determined to find a solution because I really do need some dress pants in my wardrobe.
Here's what I did. The back of the pants had darts sewn in below the waistband, so I just cut those babies open. (Please excuse the terrible pictures!)
Some super comfortable dress pants! For four bucks. Score.
