I hate to rain on your parade and all, but your hive-mind thread is slightly doomed to failure. The reason being that the achievement will only be activated if everyone that posts is wearing the EXACT SAME OUTFIT. Meaning they would also need to be wearing whatever clothing items you have on + the snowglobe in order for it to work. May I suggest stripping down to nothing but the snowglobe? Or nothing + a cheap I Am item, like Starmony; most people have that item too.
