SISTER: 5’8” | 150 lbs | wearing size S in Wood Camo ME: 5’9” | 145 lbs | wearing size S in Camo We both usually wear a medium but preferred the fit of the small. If you want a more relaxed fit, stick with your true size. The small still has some stretch with the partial elastic waistband in the back — just a bit more fitted!
