As the brand claimed and throughout many reviews online, Thinx underwear does fit true to size, so it’s okay for you to go with your normal size.

How to get the perfect measurement for your Thinx?
For not only the Thinx underwear but also every bottom is advanced, the hip measurement is the most important thing that you should pay attention to if you want to find the perfect fit. So, make sure that you’re measuring the right area:
- Waist: Measure the smallest area of your torse, which is right above your belly button.
- Hip: Your hip is around the largest of your buttocks so you need to measure the widest part of your bottom.
Pay attention to your hip measurement to get the perfect fit!
You can even check out the Thinx’s size guide where they have seven of their coworkers to wear their favorite Thinx along with the description and their regular pant size for reference!
Now with the guideline above, we hope that you will have no trouble choosing your best Thinx period underwear. Don’t forget to grab the Up to 30% OFF Thinx coupon while you are at it to save yourself a few bucks!
