Garment Fit

Alpha Camp Pants have an athletic jogger fit. Relaxed around the hips and thigh. Slim leg that tapers to a stretch-knit ankle cuff. Full rise with crotch gusset for squat comfort and easily adjusted pant length to nail the perfect fit.

For a women's fit, common adjustments may include shortening the pants rise, shortening the inseam, or adjusting the leg taper. Instructions are included based on successful independent pattern tests. Thank you @Ms.Math, @Madeby_Francesca, and @Discovery Fabrics

Body Measurements

The sewing pattern covers a wide range of sizes corresponding to men's XS to XXL. Full hip/seat is the main sizing measurement, the maximum horizontal circumference around hips and butt. See body measurements shown in photo gallery above.

Sewing Skill Level - Advanced Beginner

Alpha Camp Pants are designed for knit fabrics. While the instructions detail every step, familiarity with sewing terms and construction techniques is expected. Serging simplifies construction however a zig zag and overlock stitch work just as well to maintain stretch and finished raw edges. This is a straightforward beginner apparel pattern and stretch fabrics are forgiving. Make a prototype and have fun!
