Shirt Collar Two-Leg Petwear Pattern Generator

Add front-leg measurements to the body set

The tool uses chest, neck, back length, front-leg gap, front-leg circumference and front-leg length. Measure circumference where the sleeve will cover the leg and length from the front-leg root to the intended cuff, with the pet standing naturally.

Record your pet's actual measurements first, then consider the stretch of your chosen fabric. Stretchier fabric may call for an adjustment to circumference inputs; do not scale back length or leg gaps along with them. See the measurement guide below for measuring methods and stretch-fabric guidance.

Review the fixed shirt collar and base sleeves

This page uses a fixed shirt collar and base sleeves. Review the neckline, chest and back pieces, armhole-to-sleeve joins and matching sleeve lengths. Front-leg gap affects the chest structure and should not be compensated for by changing sleeve length.

Use a movement test to check the underarm

Make a lower-cost test and observe the underarm, neckline and cuffs while the pet stands, walks and lifts its front legs. Confirm print scale and movement ease before cutting the final material.

Each payment includes two PDF exports for the same pattern style. Make a test garment after the first export. If a measurement was wrong or the fabric stretch makes the fit too loose or tight, recheck and adjust the relevant measurements, then use the remaining export for the revised pattern.
