I imagine the most frustrating part about being a werewolf is that when you morph back into a human, you’re naked. Apart from the risk of catching a cold and being embarrassed, wearing your birthday suit in public is also illegal. Public nudity remains on your permanent record and making light of it at a job interview can be a challenge.
Unless you are a werewolf with enough foresight to strip prior to shape-shifting, you are going to shred your pants. Pants are expensive. They also are a hassle to shop for because you have to try them on at the store.
As a werewolf, you need a pair of pants with an elastic waistband and tapered ankles that will stretch and expand to fit your human body as well as your lycanthropic man-beast body. What you need are Zubaz. Zubaz for werewolves could come in many flashy patterns and also have a flap in the back for the tail to poke out.
