“runs small”

“I bought this shirt last year in a 4, my normal size, and a 6. I am 5'5" and a slim build. The 4 was a little small and especially so in the armholes. The 6 fit well but armholes were also tight. Had to return them but I liked the shirt and the fabric so much that I searched and found an 8 and bought two colors. Wonderful fabric, breathes well, freely moves on your skin, color stays true. The side vents are a little see-through. Great for hiking, and light weight for backpacking. I've worn mine to work under layers in cool/cold seasons. A little short for tucking in but has a rounded finished hem that looks great worn out. I like the length. I LOVE these shirts. If you wear a 0 or 2, the 4 may work great for you.”
