Gunner Long Sleeve T-Shirt by Katie Van Slyke®

A quick guide to long sleeve sizing so you can pick the right fit on the first try. All measurements are in inches and reflect the actual garment laid flat, not your body — so if you're comparing to a long sleeve you already love, measure that one and match it to the chart.

Long sleeves run true to size for most fans. If you're between sizes or want a more relaxed fit over a hoodie or thermal, size up. If you like a closer, more fitted feel, stay with your usual size.

Long Sleeve T-Shirt Size Chart

How to Read the Chart

Three quick measurements and you're set:

• Width is measured pit to pit (across the chest), laid flat.
• Length runs from the top of the shoulder seam down to the bottom hem.
• Sleeve, center back is measured from the center of the back collar, out across the shoulder, and down to the cuff.

The easiest way to nail your size: grab a long sleeve tee you already wear and love. Lay it flat. Measure the width pit to pit, the length top to bottom, and compare to the numbers above. Whichever row matches closest is your size.

Frequently Asked Questions

Do Katie Van Slyke long sleeves run true to size?

For most fans, yes. The cut is relaxed without being oversized, with a slightly longer body and full-length sleeves for that easy-layer feel. If you wear a Medium in everyday t-shirts, a Medium here will feel right.

How do long sleeves compare to KVS short sleeve tees?

Long sleeves and short sleeves share the same body width measurements (S = 18", M = 20", and so on), but long sleeve bodies run a touch longer for that pull-down-over-the-leggings comfort. If you've sized into our tees before, stick with the same size here.

What if I'm between sizes?

Size up. The fit is on the closer side of relaxed, and a half-size of room is always more comfortable than a half-size of tight. If you're planning to layer over a hoodie or thermal, sizing up is the move regardless.

How should I wash my long sleeve to keep the fit?

Wash cold, inside out, tumble dry low. No bleach, no fabric softener. That's the formula for keeping the print bright and the fit on lock through plenty of barn-chore wears.

Is there a separate size chart for kids' long sleeves?

Yes — adult long sleeves use the chart above. For the little farm fans, browse the kids' collection for kid-specific sizing on their product pages.
