I see two things wrong with this scenario...
1. From your post it appears that you were the only one in the group treated this harshly and it wasn't just one person. They all ganged up on you. I don't care if you are 5or 50 this is bullying behaviour. Singling someone out and being overly aggressive toward you in a group mentality. Not cool at any age!
2. They way over stepped the rules of personal space. This is just disrespectful. A whole group of people's hands grabbing you and forcefully ripping off an article of your clothing??!! Unless they were my best long time friends or sisters, IMHO, I would certainly feel violated!
A lot of people don't like to be touched by anyone they are not very close with and certainly not man-handled!
Huge Boundary violation!
I think these girls need to be sent back to kindergarten to relearn the basic ABC'S of appropriate human interaction.
But if you value them as friends, I would just tell them firmly but gently that you really are uncomfortable with that much contact. (Just leave it at that. Don't make it a big deal approach it with an air of nonchalance and see how they react) If they make a big deal out of it then they are definitely just extremely juvenile and then it's time to go find some friends who are at the same maturity level you are.
If they make a little joke about it, but then apologize in someway..then they are probably fairly decent people still with a little growing up to do...who just got caught up it the fervor of the game and took it a step too far. But they do probably value as a friend and if so... in the future they will know that is not cool with you and restrain themselves from behaving towards you like that again. Just my two cents. You can take or leave all some or none of it.
