Fun design

Fun and comfortable! There is one strap that goes from one shoulder across the other along the back. Took me some getting used to but overall happy with the purchase.

How to Measure
Grab a measuring tape, some paper and a pencil, and get started! You’ll need to find your band measurement, bust measurement, and cup size to find the bra that’s right for you.

1. Band measurement
Place the measuring tape flat across your back and under each arm. Measure across the front of your chest, just above the bust. This is your band measurement.
If the number is odd, round down to the nearest even whole number.
Example: If you measure at 35", round down to 34".
Band sizes are commonly available in size 32, 34, or 36. This is the number that comes before the cup size in bra sizing.

2. Bust measurement
Now measure across the bust and around your body keeping the tape parallel to the ground. Make sure to measure across the fullest part of the bust.
If the measurement falls on one 1/2" or greater, round up to the next whole number.
Example: If you measure 36 1/2", round up to 37".
