One top, that shows up from time-to-time on ebay and other resale clothing type sites, is Sookie Stackhouse's plaid shirt she wears in S04E01 of True Blood. The top is a J. Crew Boy Shirt in Pink & Blue Plaid.
The easiest way to find it, when it's listed, is to simply type the words "J. Crew Pink Plaid" or "J. Crew Plaid Boy Shirt". One of the key indicators of the shirt is the tag. It's 100% cotton and is in fact labeled "J. Crew Boy Shirt".
