It would be slightly dependent on how tall you are, but with your measurements I'm sure a 'size 0' would fit you quite snugly. If you're going for a baggier look then a 'size 1' would be better suited. I have a 24 inch waist and 33 inch hips, and a 'size 2' from Hollister are kind of baggy on me.
You should wear a size 10
Your jeans size.
38-bust 32-waist 40-hips
If you are talking about the ones from Old Navy, they are a bit higher waist. Not so high to be 'mom' jeans but comfy.
To tell if you have wide hips, measure your hips and your waist. If your hips are considerably larger, you might have wide hips.
Common measurements include: - Height - Bust - Waist - Hips - Low Hips - Inseam
Traditionally - bustline, waist and hips.

It's how many inches or centimeters you measure around your waist (slightly above the hips)
That is not small at all. A 46 inch waist is not petit. Now the jeans vary on your figure. Consider the size hips you have.
Your hips are at least 10 inches bigger in circumference than your waist,if your boobs are too,you're an hourglass.
Your hips are the protrusions between your waist and your thighs.
