Zelda has some continuous characteristics beyond Caucasoid build with long strawberry-blonde hair (with ranges into both strawberry, and blonde).

She has breasts, which are slightly smaller than average for someone of her build but definitely there. Also pointed, longer than normal ears. These together give her a lithe, more elven look. Despite the lithe build, she has wider hips, a pear-shape rather than hourglass-shape build.

Also, rather notably, in any rendition in which she wears tight skirts, pants, leg-wrappings, or the like, there's a notable flatness to her lower half: She has a "bikini bridge" kind of build, and basically carries no weight at all on her lower torso to upper leg. Skyward Sword in the example pics showcases it well enough, the hip widens out, and then shoom, straight down, minimal thigh definition.

She is also defined as conventionally beautiful, for what it's worth. So while casting a tomboy could work for many of the stuff, that girl'd need some extra makeup time to nail the facial appearance (and vice-versa, a more conventionally beautiful woman would likely need to use careful outfitting to get the right lithe look).
