Why are my sims suddenly wearing all cc items?

Not sure what's going on here but before the Get Together patch my townies always dressed in EA clothes and hair only.  Ok, well sometimes the odd townie would show up wearing a cc item, but today when I played Windenburg every townie was wearing cc hair and clothes including the naked bottoms and tops by cmar!

Do I have to manually open up every single piece of clothing in s4pe and change the setting to disable this? 

Does anyone have any suggestions?

Thanks guys
