No, not on the front of a shirt. Put it on the shoulder or near where a pocket would be on a shirt. Making one big SS that's plastered across the front of your chest just seems like you're screaming for attention. A subtle mark creates no doubts as to your allegiance, but also doesn't scream at everyone "HEY GUYS LOOK AT ME NOTSEE SYMBOL HAHA". Which, entirely unrelated, I really hate shirts that do that in general. Why? Because it seems manufacturers leave their logos or little quips across the upper chest. As a guy, if I'm staring at a girl's chest trying to figure out what the fuck the shirt says... Well, that's just asking for a bad time. So now their funny bullshit is worthless.
