It took me a couple of sizes to get the right one.  Keep in mind that this is a regular t-shirt and not a juniors shirt (which was my original mistake).  I ended up with a small (I'm 5'4 average build) and it fit just right - not snug and not too loose.  The graphics pretty much look like they do in the picture and I've washed it twice now and they still look crisp.  I basically wear it to bed - who doesn't want to sleep next to Matt Smith?!

I did notice that the shoulders poke up a bit.  Might just be my shirt, but it bugs me a little.  Overall shirt is good.
