My baseball cap is old so I linked similar.
I’m wearing a size small in my tee and shacket and my true size in my jeans.
My jeans are from madewell last year and sold out in this wash. I linked this year’s washes in the same style (perfect vintage straight jean).
Stay true to size if you want a looser fit and go down one for a more true to size fit. The most comfortable jeans I’ve ever worn!
