Have you ever worn this one outfit that everyone kept making offensive sexual comments about? That skirt that showed your panty line too much or those shorts that looked way too short.
Steps
Collect all clothing that seems like it attracts unwanted attention.
Think through what the issues are with each item. Can any of them be salvaged by wearing them differently? For example, short skirts or shorts may be less revealing if worn over tights. Snug T shirts could be worn under a loose blouse, etc.
Purchase alternative clothing such as Capri's instead of short shorts. Capri's are comfortable, yet cool, and they don't expose as much skin.
Avoid sleeveless shirts. Cap sleeves, short sleeves, etc help ward off unwelcome attention.
Beware of V-necks that swoop way too low. Consider layering them with something that has a higher neckline.
Avoid leggings unless there is another item covering the butt and panty lines.
Thongs can help make panty lines disappear, but can also make questions arise of why there is no panty line.
Tips
Wear more modest clothing
Your actions speak more clearly than your clothing. Consider adjusting your behavior to less provocative.
