According to Leaf TV, designers often market thongs as swim or activewear, which means they use a heavier material to create it versus what they might use for a g-string. A well-made thong might work well under your yoga leggings or other workout clothes when you're breaking a sweat. Of course, daintier versions of thongs exist, but they still have the thicker strip of fabric that flows into a v-shape at your lower back. Sarah Jenkins, head of communications and strategy for Damaris and Mimi Holliday, explained the thong to Refinery29. "It's [the thong] considered, by some, to be the G-string's more comfortable counterpart," she said. You probably use one under any outfit that tends to show a visible panty line.
The skimpiest of underwear options, often called "floss," you might choose to wear a g-string for a romantic evening out, sleeping, or as a lingerie accent piece (via Leaf TV). Negative cofounders Marissa Vosper and Lauren Schwab told Refinery29 when a g-string works best. "G-strings are useful under body-con dresses and skirts, where you might otherwise go commando but aren't quite down with that program," they noted.
One caveat for both underwear styles — you need to be especially careful with your hygiene when wearing thong and g-string panties to help avoid infections.
