How To Measure

Follow these steps for your perfect fit

1. Get a measuring tape

You can do this on your own or get a friend to help. Wear a non-padded, wired bra for best results. Always relax and make sure your arms are by your side.

2. Find your band size

Align the tape around your body at ribcage level, directly under the bust, keeping the tape parallel to the floor. Tape should feel snug but not tight around the body. Record your measurement.

Find your band size according to the measure chart.

Measurement/Band Size

27-28"	29-30"	31-32"	33-35"	36-38"	39-41"	42-44"

31-32"	36
33-35"	38
36-38"	40
39-41"	42
42-44"	44

3. Find your cup size

Wrap the measuring tape around your body at the fullest part of your bust, ensuring the tape is parallel to the floor. The tape should fit comfortably around your body. Take note of this measurement.

Then, subtract your band size from your bust size to determine your cup size.

* For instance, if your bust measures 36 inches and your band size is 32 inches, the difference is 4 inches, indicating a cup size of D.

Fits Perfectly
Fits perfectly and so comfortable. Feels like I'm wearing a bralette instead of a bra. Supportive and the fabric feels smooth.
