Stiff material. Bought a 3x because scrubs usually are right on my chest and butt. Ran very large. I had to wear this color for work so it was a quick last minute deal to buy it. Spend the money and buy something with better material. Thank God I have a seamstress in my family. I normally wear a size 18. She had to take 3 inches off the back seam and from under the arms.
