I wanted this shirt to be loose and flowy, so I ordered one size up. My usual size would have fit just as well, but I am pleased with the amount of flow I get from the medium. I would suggest ordering either in your size or up one depending on the amount of flow you would like to get from this top. I love this shade of blue, the fit, and the ruffled sleeves of this blouse! It comes in a wide variety of colors, and I plan on ordering more in different colors! I ordered a size medium in the color indigo blue.
