Lol. I guess mine really looked messed up to some people! I always use default skin replacements, slider hacks, and loads of CC. Its interesting to see how much I think it looks cool, but others think its not so cool. I actually LIKE that people have different opinions. Makes life so much more interesting
IMO though, when I don't use these things, by the 3rd or 4th generation, all sims pretty much seem to be a carbon copy of each other. I guess because I like variety so much, I prefer to use these others things.
To the OP, you should probably just experiment with it a little and see if you like it. If you don't, no harm, just remove it!
