The material is super soft and flexible. I bought a large because that's what I normally wear in scrub tips and I was following the size guide. The top was tight around the arms and shoulders and there is a 2 inch slit on each side which absolutely does not work for me because it shows skin. The scrubs are short enough as it is. Even if I sized up I don't think it would have enough length to cover my torso appropriately (I'm 6'1"). Recommend for persons under 5'9.
