Super comfy, don't ride up, high quality

Loving these undies. They don't ride up (most other seamless undies do). True to size, I'll definitely be buying more.

Love these!

I bought these while pregnant and these are amazing! I sized up and they fit perfectly. I can barely tell I'm wearing them. Great quality so I plan to buy more.

LOVE these!

First let me say, an amazing fit is hard to find for me. My favorite brand stopped making mine so it has taken me almost a year to find these!

Only reason I didn’t give 5 stars was because I prefer a cotton crotch, this material is almost like a polyester but it’s not a huge deal since the fit is perfect (size up one size)!

Best parts: No seam in the front, seam in the back isn’t noticeable / no wedgies, doesn’t bother my bikini line with seams, seam for the “crotch material” doesn’t bother me either (a real problem I have), truly seamless under leggings, and they don’t move around or give me busted biscuits feel.

I hope this helps someone who is searching for great underwear. Also, personally not a fan of the other scrunch butt underwear offered by BP.

For reference, I’m 5’8” at about 160-165lbs

Measure Your Rib Cage:

Measure around your rib cage just under your bust. Round down to the closest inch. This is your rib cage measurement, which you’ll need to figure out your band and cup size.

Figure out your band size:

Take your rib cage measurement from step 1 and read across the chart below to find your band size

Rib Cage Measurement Band Size
25" - 27" 30
27" - 29" 32
29" - 31" 34
31" - 33" 36
33" - 35" 38
35" - 37" 40
37" - 39" 42

Figure out your cup size - This is a 2-step process:

First, measure around the fullest part of your bust. Keep the tape straight across your back. Round up to the nearest whole number. This is your bust measurement.

Now, subtract your rib cage measurement (step 1) from your bust measurement (step 3). The difference in inches is your suggested cup size. If you’re between sizes, round up.

Bust Size Minus
 Rib Cage Size		 Your Cup Size
3" AA
4" A
5" B
6" C
7" D
8" DD
9" E

Calculate Your Size:

First, measure around the fullest part of your bust. Keep the tape straight across your back. Round up to the nearest whole number. This is your bust measurement.

Now, measure your rib cage. Subtract your bust measurement from your rib measurement. The difference in centimeters is your suggested cup size. If you’re between sizes, round up.

2.5 CM= A | 5 CM= B | 7.5 CM= C | 10 CM= D | 12.5 CM= DD | 15 CM= E

Fit Guidelines:

Every bra serves a different purpose for different activities and we recommend referencing each specific bra product description to determine the best bra for your body and sport. Our bras should generally fit snug. Wearing the bras too loose will not likely provide adequate support.

***Please note, a majority of our sports bras are medium support and medium coverage. If you are looking for the highest impact support that we offer; check out the X-Factor, Intensity or Moxie Sports Bra!
