I'm someone who stands at a height most people would describe as "freakishly tall."
I know firsthand the trials and tribulations of trying to purchase a shirt long enough to hide my belly button but slim enough to avoid resembling a maternity dress.
Over the years, I learned which brands to buy and which ones to avoid. For example, I tend to avoid purchasing clothes from Walmart because it assumes people who need XXL shirts have waist sizes equal to their heights (this didn't stop me from purchasing multiple graphic tees incorporating wild animals and the American flag).
One man learned the hard way when he decided to pick up some tank tops at America's Favorite Store (To Make Fun Of) and discovered the letters "XL" mean something slightly different to the people of Walmart than they do to others.
