Finding that perfect outfit takes time and dedication. Either you have to scroll through online store after online store or hit the streets and try on a bunch of different outfits. The worst part is when you find the outfit, get home, try it on and start wearing it around only to realize that it chafes. That chafing can drive a person nuts after a while, and it has to be stopped.
First, determine where it is chafing. Then, dab on some Vaseline, and the chafing should stop. Just make sure the Vaseline doesn't ruin the fabric.
