How to measure for a carrier
The DUO and H2DUO are sized based on a diagonal measurement from the ball of one shoulder to the side of your opposite hip.
Some tips while measuring:
Try to wear a fitted shirt that has a shoulder and sleeve seam as well as a
side seam that extends from your armpit.
(2) Do not go BETWEEN your chest, go over to account for it!
(3) To find the top of your hip bone go roughly an inch below your belly button around to your side.
(4) Make sure to go all the way to your side (where the seam is).
All of these will insure a proper measurement and thus avoid a remake.
