I agree. She's one of the few female characters that didn't get saddled with a new pair of giant knockers or a catsuit as the series went on. All her designs are good, especially the armored ones in ME2 and 3. I just liked that aspect (the ME1 arm) and wanted the cybernetics angle on the quarians to be played up a bit more as a theme than it eventually was.
You ignore the fact that she was given very exaggerated female porportions such as her hip to waist ratio and volumptious butt. Speaking her her butt, she got a very visual and enhanced "butt crack" line that really added visual appeal to her butt. Her look was VERY sexual.
I am not complaining but still, to say that she was "grounded" in her look is a bit naive.
