I ordered a size Medium (which is what I tend to prefer in most regular t-shirts for a slightly loose fit) keeping in mind that it would be way baggies since the shirt is meant to run baggy. I just got this shirt out of the mailbox 20 minutes ago and I am very pleased! The packaging was simple yet cute, and I received a coupon code. The shirt did fit baggy, but if you would like for it to go past your butt, then I would recommend getting a size large. I'm 115 pounds and 5'6 to put things into perspective. If you do not like the element of surprise, then this might not be the product for you. The surprise part is what added the thrill factor of waiting for this shirt, and I am quite happy.
