There is no clear direction we can point you as it really depends on your personal style preferences.
Sports G-Strings will generally only be tolerated by women who are used to wearing a G-String or Thong daily. Moving from a Sports Brief to a Sports G-String can be quite a shock so we recommend trying this around the home before heading out for a workout in a new Sports G-String.
Sports Briefs or Sports Full briefs are typically favoured by women who like to feel secure around the tummy as these are generally high coverage around the tummy.
Sports Hipsters suit those who want more coverage than a g-string, but whom don't like underwear near to or up to their belly button.
