What You Need to Know

I once ordered a Caitlin Clark jersey that fit like a tent. I’d guessed my size based on my regular shop caitlin clark merch store shirt, and the result was a wardrobe fail on game day. If you’ve ever dealt with sleeves that hang past your fingertips or a caitlin clark merch store hoodie that feels restrictive across the shoulders, this Caitlin Clark merch sizing guide will fix that. After reading this, you’ll know exactly how to measure yourself, read size charts, and pick the right fit for your body type. No more returns. No more guesswork.

Step-by-Step Guide

Step 1: Take Your Measurements with a Soft Tape

Stand straight with your arms relaxed at your sides. Measure your chest at the fullest part (just under your armpits), waist at your natural waistline (around your belly button), and hips at the widest part. For sleeves, measure from the center of your back to your wrist bone. Write these numbers down in inches. Pro tip: don’t pull the tape tight - you want a snug but not compressed measurement.

Step 2: Compare to the Caitlin Clark Apparel Size Charts

Every product on the store has its own size chart linked in the description. For cotton tees, the chart typically lists chest width (20”-22” for Small, 22”-24” for Medium, etc.) and body length. Hoodies often have added ease for layering - a Medium hoodie might have a 24” chest width versus 22” on a caitlin clark merch store tee. Jerseys follow athletic sizing: they’re cut looser through the torso but fitted in the shoulders. Always match your chest measurement to the chart’s “chest width” column, not your caitlin clark merch store shirt collection size from another brand.

Step 3: Account for Shrinkage on 100% Cotton Tees

Most Caitlin Clark cotton tees are pre-shrunk, but a small amount of shrinkage (2-3%) can still happen after the first wash. If you’re between sizes, size up on cotton tees. For example, if your chest measures 38”, a Medium (38-40”) fits now but might shrink to a 37” after wash - go for Large (42-44”) for a comfortable, lasting fit. Hoodies and jerseys are typically polyester blends and won’t shrink, so you can stick closer to your exact measurements.

Step 4: Decide Your Fit Preference

Ask yourself: do you want a fitted look or a relaxed, oversize vibe? For fitted, choose a size where your chest measurement falls in the middle of the size range (e.g., 38” chest for Medium 38-40”). For relaxed, go one size above. I always recommend checking the product photos - the model’s measurements are sometimes listed. A hoodie that looks snug on a 5’8” model will probably be roomy if you’re 5’6”.

Step 5: Check the Length for Your Height

Length is the most overlooked measurement. A tee that fits perfectly in the chest might be too short if you’re tall. Size charts list body length from the top of the shoulder to the hem. For a standard tee, aim for length around 28” (Medium) - add 1” for each size up. If you’re over 6’ tall, consider a Large or XL even if your chest fits Medium. Jerseys tend to be longer (30-32”) to tuck in, so that’s a plus for taller fans.

Step 6: Use the “Two Finger Test” for Shoulder Seams

When you try on a tee or jersey, the shoulder seam should sit right at the edge of your shoulder bone. If the seam is hanging down your arm, it’s too big. If it’s cutting into your shoulder, it’s too small. Place two fingers under the seam on each side - if they fit without tugging, your size is right. This works even without a mirror.

Common Mistakes to Avoid

Ordering your usual T-shirt size without checking the chart. Brand sizing varies wildly. A Medium in Adidas could be a Large in our Caitlin Clark hoodies. Always measure first.
Ignoring the difference between men’s and unisex sizing. Many Caitlin Clark tees are unisex, which means they’re cut wider in the shoulders and chest. If you’re a woman who usually wears a women’s Medium, the unisex Small might fit better. Check the hip measurement - unisex tees are straighter through the waist.
Assuming all hoodies fit the same. A lightweight pullover hoodie has a different cut than a heavyweight zip-up. The zip-up hoodies tend to be more fitted because of the zipper structure. Go by the individual product chart, not a generic assumption.
Forgetting about layering. If you plan to wear a hoodie over a shirt, size up. But if you want a jersey over a hoodie, the jersey needs to be at least two sizes larger. A Large jersey over a Large hoodie will be too tight in the arms.

Pro Tips from the Community

Measure your favorite fitting shirt. Lay a T-shirt that you love the fit of on a flat surface. Measure the chest width (pit to pit) and the length. Compare those numbers directly to the size chart. This eliminates guesswork completely.
Consider the “Active Fit” for jerseys. I’ve found that Caitlin Clark jerseys look best when they’re slightly loose in the body but snug in the shoulders. The motion cut allows for free arm movement - if the jersey is too big, the shoulders look sloppy. Stick to your chest measurement exactly.
Check the fabric weight. Our 6 oz. cotton tees hold their shape better than lighter 4 oz. tees. A heavier fabric is less likely to stretch out, so you can buy closer to your true size. For lighter tees, size up if you want a relaxed fit.
Use the size chart’s “Inseam” if you’re buying shorts. Often forgotten, but shorts sizing is based on waist and inseam. Most Caitlin Clark shorts have a 7” inseam - if you prefer longer, size up to get an extra inch.

Key Takeaways

Measure your chest, waist, hips, and sleeve length with a soft tape.
Compare those numbers to the individual product’s size chart - never assume.
Size up for 100% cotton tees to allow for minimal shrinkage.
For jerseys, match your chest exactly and check shoulder seam placement.
When between sizes, preference for fit and your height should guide the final decision.

Frequently Asked Questions

How do I measure my chest for Caitlin Clark apparel?

Wrap a soft measuring tape around the fullest part of your chest, just under your armpits. Keep the tape parallel to the floor and snug but not tight. Round to the nearest half inch. That number is your chest measurement.

Are Caitlin Clark tees pre-shrunk?

Most cotton tees in the store are pre-shrunk, but some shrinkage (2-3%) can occur in the first wash. Polyester blends like jerseys and performance hoodies don’t shrink. Check the product description for fabric content.

What size should I get if I’m between sizes?

If you prefer a fitted look and the smaller size’s chest measurement is close to yours, go with the smaller. If you want room to move or plan to layer, choose the larger size. T-shirt length is also a factor - taller fans should lean up.

Do women need to size down for unisex Caitlin Clark gear?

Yes, often. Unisex sizing has a boxier cut with broader shoulders. If you typically wear a women’s Medium, try a unisex Small first. Compare the hip measurement on the chart - if the unisex Small’s hip is close to your hip measurement, it’s a good match.
