These are actual shirts at a clothes shop I have seen for women. They basically come in different colours and are plain apart from the writing.
"I'm busy. you're ugly. have a nice day."
"Don't piss me off, I'm running out of places to hide the bodies."
"Guy's have feelings too but like... who cares?"
"I don't believe in miracles. I rely on them"
"All stressed out and no one to choke."
"I can go from zero to bitch in 3.6 seconds."
"I'm not just a bitch. I'm THE bitch. And that's Ms. Bitch to you!"
"I'm multi-talented. I can talk and piss you off at the same time."
Those, my friend, are the greatest shirts in history.
