Hubby gave me a pair of old jeans that didn't fit him anymore for the refashion pile. My toddler son needs some new pants so I just made him a pair of elastic waist jeans with the tried and true Simplicity 3765 pattern.
Since the pattern piece has no outside seams, I cut open the inseam and placed the pattern so that the original outside seams of the jeans were preserved. I topstitched a faux fly for the front. A quick and easy refashion!
