I usually wear a 3X, and decided I want a roomier tank for the summer (like I'd look skinnier in a looser fit....WHAT?).  The reviews say this tank runs large, so I ordered a 3X figuring it would be bigger...like a 4X.  OMG!  The arm holes are so huge that you can run a mack truck through them!  GINORMOUS!

On the lighter side, as I put it back into the box and taped it up for its return ride I noticed that this tank seems to be of good quality.  Kudos to Amazon Prime!!  I got no hassle about the return, no fees for restocking or shipping.
