Sorting Out Sizing

Wrong size example - ask for help

Don't let this happen to you!

While this fit may make for a funky after diving dinner outfit, this not what you want on a normal day.

Scuba Sisters promptly sent her a size better suited for her body. If you are part of the Girls That Scuba Facebook Group, you may have seen the hysterical post where we all had a great laugh about this!

Follow this simple guide to determine which of our products will fit you best.

We have all run across differences in sizing from different manufacturers. You buy one size and it fits fine. Then you buy what seems like the same style in a different brand in the same size and you can't even squeeze into it. FRUSTRATING to say the least.


Step 1: Measure your waist, hips, and inseam

  • Waist: typically right around your belly button. Bend to the side and where the natural crease appears is your waist.
  • Hips: the widest point of your hips and buttocks.
  • Inseam: from your crotch to your ankle.

Write down or remember these numbers!



Step 2: Consult product descriptions and size charts while shopping

  • Use your measurements from Step 1 to select the best fit.
  • If you find the size chart does not align just right, lean towards the hip measurement to select your size.
  • Take note of whether the description states mid or high waist based on your personal preference.
  • Take a look at the inseam measurement. You can always bunch them up a bit if they are longer.
  • NOTE: If the leggings feel loose when dry, they will likely be too big in the water as every fabric becomes looser when wet!




Tops (including rash guards)

Step 1: Measure a similar shirt you love

  • Grab a shirt that fits you well that is a similar style (ex. tank top if you are buying a tank top) and a tape measure.
  • Measure the Width and Length according to the diagram below.

Write down or remember these numbers!

Step 2: Consult product descriptions and size charts while shopping

  • The description for each product will let you know details about the styling of the shirt (slim fit, relaxed, etc.). If slim fit shirts don't normally fit you well, look for one that is relaxed instead.
  • After you determine the style of shirt you want, open the size chart and match your measurements to the size for that particular shirt. Aligning measurements is important as each manufacturer and style results in different measurements.
  • NOTE: If the rashguard feel loose when dry, it will likely be too big in the water as every fabric becomes looser when wet!
