Plus-Size Ugly Christmas Sweaters: How to Find the Right Fit

Finding a plus size ugly Christmas sweater starts with one measurement: your chest at its fullest point. Compare it with the size chart on the product page and size up if you want a relaxed fit or plan to layer. Our knit sweaters go up to 3XL, and our all-over-print sweaters go up to 5XL.

How do you measure yourself for an ugly Christmas sweater?

You only need a soft measuring tape and about two minutes. Stand relaxed, wrap the tape around your chest at the fullest point, keep it level across your back and snug but not tight, then note the number. Do not pull the tape in or hold your breath: you want the measurement you have when you are standing at a party, not your smallest number. If you usually wear a shirt under your sweater, measure over that shirt. Now compare the number with the size chart on the product page of the sweater you like, not with the size you wear from another brand. Sizes vary between brands and styles, so the chart is the reference that counts. If your measurement falls between two sizes, choose the larger one for a relaxed fit. A second check helps too: lay a sweater you already love flat, measure across the chest from armpit to armpit, double that number and compare it with the chart as well.

How does unisex sizing fit if you're plus size?

Our sweaters are unisex and true to size. Unisex sizing follows a men's-style cut, which is generally straighter through the body than a women's cut and is not shaped at the waist. That has two practical effects for plus-size shoppers. First, the chest measurement is the one that matters most: if your bust is the widest part of your upper body, choose your size from that number on the chart. Second, a straight cut falls past the waist toward the hips, so if your hips are wider than your bust, it is worth sizing up for extra room around the hem. Shoppers who usually buy women's sizes often find that the letter on the label does not translate directly to unisex, so set aside the size you normally buy and go by your measurement instead. Whenever you land between two sizes, size up for a relaxed fit rather than squeezing into the smaller one.

Should you choose knit or all-over-print for plus sizes?

Both styles suit the same holiday parties, so the choice comes down to the look you want and the size you need. Our knit sweaters are real jacquard knit in soft acrylic yarn, with the pattern knitted into the fabric rather than printed on top. They have a relaxed unisex fit with room for a layer underneath and come in sizes S–3XL, and you can browse them in our ugly Christmas sweater collection. Our all-over-print sweaters are made from 260 g/m² sweater-knit polyester, a midweight fabric, with the design printed by sublimation across the whole sweater. They cover the widest size range we carry: Adult S–5XL, plus Youth 2XS–XL if you are shopping for the whole family. If you need 4XL or 5XL, start with the all-over-print sweaters. Whichever style you pick, open the size chart on that product page before you order and compare it with your chest measurement.

What can you wear under a relaxed knit sweater?

Our knit sweaters have a relaxed unisex fit with room for a layer underneath, which makes layering one of the easiest ways to stay comfortable at an indoor party. A fitted T-shirt or a long-sleeve tee is the simplest base: it keeps the knit off your skin and adds warmth without bulk. A collared shirt works well for an office party, with the collar showing at the neckline and the cuffs folded over the sleeves. A camisole or tank top is enough if the room will be warm. Skip chunky hoodies or thick turtlenecks under a knit sweater, because they add bulk at the shoulders and can make the sweater feel tighter than its size. If you know you will always wear a layer underneath, that is a good reason to size up when you are between sizes, and to take your chest measurement over the layer you plan to wear.

What happens if your sweater doesn't fit?

Sizing online always carries some uncertainty, so it helps to know how returns work before you order. Every order is covered by our 30-day return policy, which means you can request a return within 30 days of delivery, as long as the sweater is unworn and still has its tags. Try the sweater on as soon as it arrives rather than the night before your party, and keep the packaging until you are sure about the fit. That leaves you time to send it back and order a different size if needed. Plan delivery into that decision as well: in the US, knit sweaters typically arrive in 5–6 business days and all-over-print sweaters in 13–18 business days. These are estimates, not guaranteed dates, so ordering early in December gives you room to reorder before the event. Before you send anything back, compare the sweater with your measurement and the size chart once more, because it makes choosing the next size much easier.

If you like a classic jacquard look and your size is within S–3XL, a knit sweater is a natural choice. If you need 4XL or 5XL, or want one design across adult and youth sizes, all-over-print gives you more room. Either way, the steps are the same: measure your chest, compare it with the size chart on the product page, and size up for a relaxed fit or a layer underneath. Order early enough to try the sweater on before your party, and remember that the 30-day return policy is there if the fit is not right.

FAQ

Do ugly Christmas sweaters run small?
Ours are true to size, so start from your actual chest measurement instead of sizing up out of habit. Check the size chart on the product page, and choose the larger size only if you are between two sizes or want a relaxed fit.
What size ugly Christmas sweater should I get if I'm between sizes?
Size up. The larger size gives you a relaxed fit and leaves room for a shirt underneath.
Do you have ugly Christmas sweaters in 4XL or 5XL?
Yes, in our all-over-print sweaters, which come in Adult S–5XL and Youth 2XS–XL. Our knit sweaters go up to 3XL.
Are unisex sweaters different from women's sizes?
Yes. Unisex sweaters follow a men's-style cut that is straighter through the body, so the letter you wear in women's clothing may not match. Go by your chest measurement and the size chart instead of the label.
Can I return a sweater that doesn't fit?
Yes. Every order is covered by our 30-day return policy: request a return within 30 days of delivery, with the sweater unworn, tags attached and in the packaging it arrived in.
