I bought this shirt in the light pink colour in a size medium as I didn't want it to be too baggy. I am usually a size large or medium in clothes from Reitman's. I love the look of the top. It is slightly shorter, so I'd recommend getting the large if you are like me and choosing between M or L, if you don't want a fitted look. I like the fact that you can wear the twist detail in the front or back and it looks good both ways.
