Thought I had this covered, but looks like I didn’t look hard enough. Stylin Online now has Serenity cast shirts in small to xtra-large, with the Big Damn Heroes front and center. TFAW.com has the same design on a blue shirt available for preorder.
Also in t-shirt news, MakeUsSmile Tees now has the Fruity Oaty Bar shirt in Women’s Jr sizes, and AllPosters.co.uk now carries the Blue Sun shirt along with the Serenity logo tee. Tip of the cap to Frieda for the heads up!
