Below: The first plaid shirt (Forever 21) I purchased from ebay, but I am still waiting for it to arrive. It looks similar to the Eclipse shirt (when Bella is on the mountain asks Jake to kiss her), except it has longer sleeves.
The second plaid shirt is dark purple...I totally regret buying this shirt.
The third plaid shirt is red and grey and looks similar to the red plaid Hollister shirt from Eclipse- when Edward and Bella are making out. I got this shirt from Target.
