posted by: O2BnSFI'm looking to get my first pair of Amoresy swimming briefs and the sizing is in cm and not inches. I'm about a 30 inch waist in jeans. According to Google, 30 inches in cm is equal to 76. So, do I get a small or size up to a medium? https://amoresy.com/products/atlas-sheer-swimming-briefs-thong?variant=43434899046579
