I love this shirt. I wish I had went with the size I normally wear. If you wear a medium t-shirt in mens as a women then a medium will be fine. I ordered a large due to what the website suggested when I wear a medium. I love how people will stop and read my shirt. I wear it to work a lot and I feel it sends good vibes. We work a lot of hours and sometimes we need a positive thing to make our day better.
