How to measure women's loose pajama pants

Measurements are in inches and centimeters. Due to manual measurement, there may be a difference of 1-3 cm.

5. Quick Tips for Measuring

Bust: Measure around the fullest part of your chest, keeping the measuring tape horizontal under your arms.
Waist: Measure around your natural waistline (usually the narrowest part of your torso, where your body bends side to side).
Hips: Stand with your feet together and measure around the fullest part of your hips/backside.
Lengths: Shirt length is measured from the highest point of the shoulder down to the hem. Pants length is measured from the waistband straight down to the bottom ankle cuff.
Pajama Pants (Pajama Pants Size Chart): Waist, Hip and Leg opening are measured around the garment (full circumference, not half). Length is measured from the top of the waistband straight down to the hem. Waistbands are elastic with a drawstring, so the waist stretches a little.

DESCRIPTION

A Fist Bump With His Cat, Printed On A Cozy Pair

These personalized pajama pants celebrate the bond between a cat and their favorite human. The original cartoon print shows a human fist giving a fist bump to a cat's raised paw, with his name on the shirt cuff and the cat's name right next to it, under the "Best Cat Dad Ever" lettering. Black palm tree silhouettes, little stars and paw prints fill the rest of the pants on the solid background color you choose.

Pick each one's breed look (Shorthair, Longhair, Scottish Fold or Sphynx), coat color or pattern (tabby, tuxedo, calico, tortoiseshell, point colors and more), eye color (Hazel, Black, Blue, Brown, Hazel-Yellow, Yellow, or one yellow and one blue eye), and name (up to 15 characters).

HOW IT WORKS

1. Upload Your Photo

Upload one clear, high-resolution photo with one face per image for the best print quality. Good lighting and a front-facing photo will help create the best result.

Best results: One face per photo, high resolution, well-lit, and unobstructed.

2. Personalize Your Order

Choose your size, and personalization options before adding your order to the cart.

3. Photo Review

Before production, our design team reviews your uploaded photo and personalization and may make minor placement adjustments when needed for the best result. If your image isn't suitable for printing, we'll contact you by email and ask you to upload a better photo before your order moves forward.

Live preview is available on all products currently offered on our website. It helps you visualize your personalization but is not a final production proof. After checkout, our design team may make minor adjustments to face placement, scale, cropping, or positioning so the personalization works better with the surrounding pattern. The final printed product may therefore differ slightly from the preview.

4. Made to Order

After design review, your custom order moves into made-to-order printing, cutting, sewing, and quality inspection.

5. Quality Check & Shipping

After a final quality inspection, your order is securely packaged and shipped with tracking information so you can follow its journey to your door.

Every personalized pajama set is professionally printed, carefully sewn, and inspected before shipping to ensure excellent quality and a beautiful finished product.

Photo Processing	Every uploaded photo is reviewed and optimized by our design team. We adjust placement, crop, sizing, and remove backgrounds when needed for the best print results.
Color Accuracy	Color-calibrated printing equipment is used for vibrant, consistent results. Slight color variations may occur due to different screen settings and the fabric printing process.
Stitching	Each pajama set features reinforced stitching and neatly finished seams for lasting durability and everyday comfort.
Quality Control	Every order is inspected before shipping to verify personalization, print quality, fabric, stitching, and overall craftsmanship.
