📐 The Basewear Size Guide: Measure Your Perfect Fit

One size does not fit all, and it shouldn't have to. We’re re-defining the way we fit the modern female body to take into consideration those things the big companies forgot about (like muscles, duh)! This isn't your mother's sports bra so it can affect your standard measurements. Don’t worry - we got your lats! 💪

Let’s get to know your size.

Did you know that more than 75% of women are wearing the wrong size bra? Yea, we didn't trust the lady at the mall either. Grab a piece of string or measuring tape and take matters into your own hands by following the steps below.

  • Step 1: Measure your chest
  • Step 2: Measure your band size
  • Step 3: Do a little math

Step 1: Measure your chest

Measure your chest just over the center of the breasts.

Handy Tip: If you don't have measuring tape you can use a piece of string, and measure it against a straight ruler.

Use the measuring tape to wrap around the fullest part of your breast, which likely runs just above or on the nipple and above your lats. Make sure to shed your current bra and don your birthday suit for the most accurate measurement. Remember to keep the tape parallel with the ground, and measure with a gentle exhale. Round down to the nearest whole number and write down your chest measurement to use in the next steps.

Step 2: Measure your band size

Measure your band just below the breasts.

Measure your band just below the breasts.

Next, wrap your measuring tape around your torso just below your breasts after a gentle exhale. Make sure the tape remains parallel to the ground. Round down to the nearest whole number and use your band measurement to determine your size in the chart below.

🌶️ Wait a hot tamale! What do these “relaxed” and “compression” terms mean?

Since the TOURA is bringing a broader spectrum of sizing than a traditional sports bra or swimsuit, you may choose a fit that's optimal for you!

  • “Relaxed” fit will feel naked on your body. You’ll forget it’s there!
  • “Compression” fit will give the girls a nice hug. Strong support, more coverage, but still room to breathe.

Step 3: Do a little math

Here's the easiest homework you've ever aced! Plug the measurements you just took into the equation below to get your TOURA Cut recommendation.

Chest Measurement - Band Measurement = Cut Size

Cut Size Recommended TOURA Cut

Chest Measurement - Band Measurement = Cut Size *Use your chest and band measurements above to calculate your “Cut Size”.

0 – 2" TOURA Low Cut

*The Low Cut is not recommended for inversions or high impact activities. If you are at all worried about the dreaded “nip slip” we recommend going with a High Cut, regardless of your measurements.
