Center front shoulder straps

I'm sewing a sundress with a straight rectangle front and shirred back. I want to try 1" shoulder straps that start in the center front, sewing them overlapped at the center, in a v, on the wrong side of the center front bodice that is interfaced. They will go over the shoulders and tie at the sides in the back about 3" from the center on each side. I cannot find instructions or information when I Google. Is it comfortable for the child? Will there be an issue of them lying flat up the front then over the shoulders? Will they support the bodice and weight of the front of the dress as well as regular straps that start 3" from the center?
