How to Measure for the Perfect Fit

Avoid body circumference confusion. Measuring a flat garment is the fastest and most foolproof way to pick your exact size.

01

Select Your Favorite Sweatshirt

Pick a crewneck sweatshirt or hoodie from your closet that currently fits you exactly the way you like.

02

Lay It Completely Flat

Spread the garment out on a smooth flat surface such as a table or hardwood floor. Smooth out any major wrinkles without stretching the fabric.

03

Measure Chest Width (Armpit to Armpit)

Using a measuring tape or ruler, measure straight across the chest from the bottom seam of one armpit to the bottom seam of the opposite armpit. This single number is your flat Chest Width.

04

Match with Our Size Chart

Find the closest Chest Width number in our table above. If you fall between two sizes or plan to wear multiple thick thermal layers underneath, we recommend sizing up one level.

Common Questions

Frequently Asked Sizing Questions

Quick answers to help you choose the right fit before placing your custom print-on-demand order.

Are these sweaters unisex or tailored for men/women separately?
All sweaters at Ugly Sweater Store feature a standardized unisex cut. Men will find the fit true to their standard US retail size. Women who prefer a fitted, tailored silhouette typically size down one size, while those seeking a relaxed or oversized boyfriend fit order their normal size or size up one level.
What should I do if I measure between two sizes?
If your flat chest measurement falls between two sizes, we recommend sizing up to the larger option. A slightly looser sweater allows room for comfortable layering over t-shirts and thermals during cold winter holiday events.
Can I exchange my sweater if I pick the wrong size?
Contact support to receive a 50% discount voucher toward a replacement order. The original item does not need to be returned.
Will the sweater shrink after being washed and dried?
No. Our high-grade polyester brushed fleece blend is inherently shrink-resistant and anti-wrinkle. Following our care instructions (cold wash on gentle cycle, tumble dry on low heat) will keep your sweater's dimensions stable season after season.
