Find Your Perfect Fit
Throughout the design process, for every size we developed we worked with multiple models. And then we based our underwear sizing chart on 40 unique body types, so you can be confident you're getting the right fit.
Note: Each of these photos is a different model wearing a different size pair of underwear. We've included the measurements for each of these models, to give you a better idea of how our underwear might fit when you're wearing it.
What to Expect from Bikini and Hipster
Bikini and hipster underwear are both a mid-rise fit, with the hipster offering more coverage. The 3/4" stretchy lace waistband lays flat against the skin and lace trim minimizes tightness.
Underwear Fit
Base Your Size on Your Measurements, Not Your Pant Size
For the most accurate fit, we recommend using your measurements rather than pant size. The pant sizes are listed as a guideline, but pant sizes can vary greatly across different brands and manufacturers. If you have a tape measure, this will be easy. If not, there are still ways you can measure.
How to Measure without a Tape Measure
If you don't have a tape measure, you can take your measurements with a string and a ruler. Simply wrap the string around your hip or your waist and mark where the two ends meet. Once you've done that, you can lay your string down and use a ruler to measure from the end to the mark.
Where to Measure
- Waist - Measure at the smallest point. This is usually higher up than where your pant waistline is
- Hip – Measure across the fullest portion, over your rear
If this isn’t the best fitting underwear you’ve ever worn, feel free to return it within 90 days of purchase. Read our return policy here.
Sock Fit Guide
Knee High's and Women's Crew Socks
Our socks are designed to be stretchy and accommodate a wide range of sizes! The complexity of a design will decrease the stretchiness, but generally, most women's socks will fit a women's US shoe size 5-10 and men's shoe size 3.5-8.5.
STRETCH-IT™ and Men's Crew Socks
Our Men's socks are designed to be stretchy and accommodate a lot of different feet! The complexity of a design will decrease the stretchiness, but generally, most men's socks will fit a men's US shoe size 7-13 and women's shoe size 8.5-14.5.
Our STRETCH-IT™ Wide Calf Knee Highs are made on a special machine that gives them incredible stretch without distorting the designs. They'll generally fit a men's US shoe size 7-13 and women's shoe size 8.5-14.5, and up to a 21" calf.
HOWEVER, due to the stretchiness, they fit a huge range of calf and foot sizes and look great. A survey of our loyal STRETCH-IT™ fans showed us that 2 out of 3 fans wearing these socks self-reported having a 15-inch calf and wearing a US women's size 9 shoe. All folks we surveyed own and love multiple pairs of our STRETCH-IT™ socks! They'll also go higher up on the leg, so they're perfect if you're taller and looking for a comfortable awesome knee high sock.

Our no show socks (or loafer socks) have serious stay-on power and are available in three sizes:
Small: Women's Shoe 6-8 / Men's Shoe 4-6

Kids Socks
Our kid's socks are soft, stretchy and ready for little feet! The Toddler socks fit children's shoe size 4-7 or ages 1-2 and feature non-slip silicone padding to help keep your little one on their feet. The Youth socks fit children's shoe size 8-13 or ages 3-6 and the Junior socks fit children's shoe size 1-5 or ages 7-10.
