Great, snug on arms if you have bigger arms
Color: Red Navy Gingham, Size: Large
I had no issues with the fit as it was true to size. Large is snug on the arms if you have bigger arms.

⭐️⭐️⭐️⭐️⭐️ – Great Fit and Style for Casual Nights Out
Color: Navy Gingham, Size: Large
Use case: Casual wear, transitional weather 👕 Fit & Feel I’m really impressed with the cut of this shirt — it’s slim fit, but still relaxed and comfortable enough for casual settings. I prefer to wear it untucked, and it lays just right for a clean, stylish look. 🎨 Style & Material Color and pattern are on point, making it versatile for evenings out. The high cotton content feels soft, though I’ve avoided using a dryer to prevent shrinkage. Fabric is breathable and suitable for transitional weather — not too heavy, not too light. ✅ Final Thoughts Overall, this is a stylish and comfortable shirt that looks great and fits well for taller builds. I’d definitely order more in different patterns.

Nice color, lightweight, but runs small
Color: Blue Gingham, Size: Large
Nice cookie and can be work tucked or untucked. The material isn’t best quality but it’s about as expected for a shirt this price range. The size runs small so buy a size up from what you normally do. Expect some shrinkage is well. Otherwise it’s a nice shirt!

Not the best fit
Color: Navy Gingham, Size: XX-Large
I like the design and color of the shirt. It runs small, I went up a whole size and the shoulder width is still a little tight. The fabric is also has small fibers all over it.
