Actually I would say that you would do well enough with a shoulder holster provided you practiced!
You might notice that "wide" folks have some difficulties drawing from crossdraw shoulder holsters.
Women find some pretty good use for shoulder holsters, hips and belt holsters can be a real pain. Many women possess rather slight builds and benefit greatly from the weight redistribution.
There are shoulder rigs that have a strap that runs around the waist to keep things tighter.
Galco rigs are of course, iconic, but you have to find one that fits you very well.
