Do you have one to show us, front and side? That might be best.
In my experience (though I am not an apple, so take this FWIW) A lines vary in their workability. The cut varies in width, which matters, and also, the fabrication makes a difference. Stiff ones are tougher to wear (for me) than softer ones.
When I was a curvier hourglass with pear tendencies I LOVED A lines. Now that I am a much more rectangular hourglass, they have to earn their keep, and they don't, always. But they are wonderful when they do work because they're so comfy, and in summertime they just let in the breezes.
