These are the Tell Tails buckle-on dinosaur tails available from fashion retailer ASOS. They come in black (currently sold out) and green and cost around $40. They attach around your waist via an adjustable elastic strap and plastic buckle. Obviously I just bought one and have been staring at myself in the mirror for the last half hour. Not gonna lie, I'm feeling pretty sexy. "Put some pants on." Dinosaurs don't wear pants. "You're not a dinosaur, just a creep drooling at himself in the mirror wearing a cheap dinosaur tail." Now you wait just a minute -- $40 isn't cheap.
Keep going for a shot of the other color.
Thanks to Lizzy, who knows what I like, including submarine sandwiches.
