Underthings are a vital part of our daily clothing routine, but sometimes it can be challenging to come up with alternate ways to say it. Well, here are a few alternatives that you can use next time you're feeling stuck. One option is "lingerie," which might sound fancy but refers to undergarments worn by women. "Undergarments" themselves are a more formal alternative to underthings, while "unmentionables" lends an air of intrigue and mystery. For those who prefer a more lighthearted term, "unmentionables" is a great option. Finally, "intimates" is a popular synonym for underthings that sounds both romantic and practical.
