Complete Guide Overview
Finding the right size in a merch drop is half the battle. You want that perfect fit - not too tight, not too baggy, just right for lounging, running errands, or filming your own content. That's exactly why we put together this Caitlin and Leah merch sizing guide. Whether you're eyeing the Caitlin and Leah Classic T-Shirt or the cozier Premium Hoodie, we'll walk you through everything you need to know to order with confidence.
Caitlin and Leah are all about comfort. They've mentioned in their recent "What's in Our Merch Drawer?" video that they design every piece to match the kind of comfy, laid-back style they actually wear. That means their sizing tends to run relaxed, but not oversized. If you're between sizes, the answer depends on which product you're looking at.
We're covering the four main pieces from their 2026 summer collection: the Classic T-Shirt, Premium Hoodie, Polo Shirt, and Tank Top. Each one has its own unique fit, so let's break them down.
How to Choose
Caitlin and Leah Classic T-Shirt Sizing
The Classic T-Shirt is the foundation of the whole merch line. It's made from 100% ring-spun cotton, pre-shrunk, so you don't have to worry about it shrinking up after the first wash. The fit is a relaxed unisex cut - meaning it's not fitted to one gender, but designed to look good on most body types.
For most people, we recommend ordering your normal size. The tee has a bit of room through the chest and shoulders, so you can move freely without feeling like you're wearing a tent. If you prefer a slightly more tailored look, you might size down. If you're looking for that cozy, oversized vibe, size up and pair it with some bike shorts.
Here's a quick breakdown:
| Size | Chest (inches) | Length (inches) | Sleeve (inches) |
|---|---|---|---|
| XS | 32-34 | 27 | 7.5 |
| S | 35-37 | 28 | 8 |
| M | 38-40 | 29 | 8.5 |
| L | 41-43 | 30 | 9 |
| XL | 44-46 | 31 | 9.5 |
| XXL | 47-49 | 32 | 10 |
Note: These are garment measurements, not body measurements. If your chest is 40 inches, you'll want the Medium or Large depending on how fitted you like it. Caitlin and Leah often talk about how they size up for a more relaxed look - you'll see that in their own styling.
Premium Hoodie Sizing
The Premium Hoodie is your go-to for chilly days and cozy nights. It's designed to be a bit roomier than the tee, with a soft fleece interior and a relaxed drop-shoulder silhouette. We've noticed this hoodie runs true to size, but because it's meant to be layered, you have a little more flexibility.
If you're someone who likes to wear a hoodie over another hoodie (we see you), go ahead and size up. If you want a clean, fitted look that's still comfortable, stick with your usual size. The hoodie is pre-shrunk as well, but because of the fleece, it might shrink slightly if you put it in the dryer on high heat. We recommend washing it cold and hanging it to dry to keep that perfectly broken-in feel.
Caitlin and Leah actually talked about their own hoodie sizing in their recent "Cozy Q&A" livestream. Leah mentioned she always takes her usual size in the hoodie, but Caitlin prefers to go one size up so she can steal it. So think about how you like to wear your layers - that'll decide your size.
Polo Shirt Sizing
The Caitlin and Leah Polo Shirt is a bit different. It's styled more like a classic golf polo - with a collar and a button placket - so it's designed to have a sharper, more tailored fit. If you're between sizes, we suggest sizing up for this one. The polo is made with a cotton-poly blend that has a little bit of stretch, but it's not as forgiving as the tee.
Measure the chest and compare it to the size chart. If you're right on the boundary, choose the larger size for a comfortable, breathable fit. This is the piece you'll reach for when you want to look put-together but still feel like you're wearing pajamas.
One thing to keep in mind: the polo is more fitted through the shoulders and arms, so if you have broader shoulders, definitely size up. Caitlin and Leah wore the polo during their recent "Summer Golf Challenge" video, and fans immediately noticed how sharp it looked. That's the vibe you're going for here.
Tank Top Sizing
Finally, the Tank Top. This is the summer essential, and it's meant to have a relaxed, breezy fit. It runs smaller than the t-shirt, so we recommend sizing up if you're looking for full coverage. The straps are slightly thicker and the armholes are cut a bit higher, so you don't have to worry about adjustments.
If you're using this for a workout or just lounging, the same rule applies: size up if you want room to move. The tank top is also great for layering under an open flannel or a lightweight jacket.
In their "Summer Haul" video, Caitlin and Leah both wore the tank top in a size up from their usual tee size, and they mentioned it was the comfiest thing they own. So take that as a hint.

FAQ
How do I know my size for Caitlin and Leah merch?
Measure your chest, waist, and hips, then compare them to the size chart on each product page. Since the Classic T-Shirt is unisex, it runs relaxed, while the Polo Shirt is more fitted. If you're between sizes, we recommend sizing up for a more comfortable fit.
Does the Caitlin and Leah Classic T-Shirt shrink?
No, it's made from pre-shrunk 100% ring-spun cotton. However, to keep it in perfect shape, we recommend washing in cold water and laying it flat to dry. Using a high-heat dryer on any cotton garment can cause some shrinkage over time.

Yes, the Premium Hoodie is available from XS to XXL. It runs true to size with a relaxed fit, so if you usually wear a Medium in other hoodies, you'll likely be a Medium here.
