I wouldn't call it superstition, well, maybe so, but I have a camo shirt Ive had since I was 16 and a size XL....now Im 27 and probably a 3XL. The shirt it tattered, torn, and cuffs of the sleeves frazzled, but Ive killed a ton of deer in it. I some how squeeze into that shirt. THe odds are probably increased, as I wear it a lot, but what the heck.
