Hello, I have recently just installed EUP menu, Law and Order, as well as Serve and Rescue. The only thing is whenever I go onto a female character and select the cops with short sleeves the skin goes through the shirt. How would I fix this?

In simple and fast terms, change the top or the "uppr" body in the EUP menu. This is pretty common as it just means the components you have do not align with each other very well causing clipping. Make sure to save the outfit so you can change back to it when you leave and re-enter game.
