tip form Sara :) about the dancing prince of SM Town
I'm entirely sure which performance Taemin wore this t-shirt. All I know is that he wore it during a SM Town 2010 performance in Seoul on 100826. From Muse's official store called Muse Explode June - Sept 2010 Tour T-Shirt. Available for both women and men at 18 Euros.
