How do I remove possible mold spores on clothes so I don't bring them into my home?

Wash/dry thoroughly. Unfortunately, molds and fungus are ubiquitous, that is, found everywhere. There are number of natural compounds to kill yeast and mold. White vinegar, tea tree oil, citrus oil, peroxide, and baking soda are all mild, natural mold killers. Beyond that, thoroughly drying clothes so that they are not folded and put away wet will keep mold from accumulating on the clothing in your drawers.
Molds love moisture. The best way to eliminate molds from clothing is the keep the material dry.
