If you watch the commercial (available at youtube.com), the real shirts have a swoosh that extends from the T to the middle of the E. It only came in an adult (mens XL) or youth/women size (mens medium). They don't have tags and many sellers are sending their ticket stubbs.

If you're like me and want one to wear - buy a cheap knock off

If you want one to collect - do it right and double check to see what you're bidding on. There are too many knock-offs for clothes on eBay to spend $50+ on a fake. It would be nice if we call sellers out for trying to scam people and watch out for rookies who don't know better.

To the guys running the scams - be honest, people will pay $20-30 for a replica and you can make a killing. Don't ruin eBay by ripping people off.

I'm trying to figure out a way to provide a replica without incurring the wrath of Nike. If I can't, maybe an honest seller can figure something out. Good luck.
