I'm usually a size medium but when I tried it on it was a bit too loose so I bought a small. I washed it in the gentle cycle in cold water and laid it flat to dry. It shrunk. Instead of a loose fitting blouse, it is now a fitted blouse. Which is fine because I can wear it under a cardigan or blazer but I wanted a loose blouse. I really love the pink colour & the material. It was still on sale so I ordered a medium online. I recommend you stay to your true size even if it feels too big.
