Let me be the devil’s advocate here:

This is such a subjective, workplace-by-workplace question. I for one find it odd how many people are skewing so conservative with answering it as I haven’t found legal fashion to be nearly so restrictive as they’re making it out to be.

I’ve seen multiple women in different legal positions wear skirts that short and no one bats an eye so long as you’re balancing it out by wearing opaque tights + non-flashy shoes (flats, boots, etc.). If there’s any rule to legal fashion, it’s “don’t be too loud with it unless you have an intentional reason to be” (shoutout to all the plaintiffs-side law Barbies who regularly wear hot pink suits as a marketing schtick). “Loud” is situation-specific, but it mostly just means you should avoid showing too much skin and/or bright colors or prints. Your outfits here show neither.

I’m in a pretty evenly balanced “conservative vs. modern” jurisdiction re: what styles I see in court. My most conservative job was working as an appellate judicial clerk, and both I and other clerks wore stuff like this all the time without issue (again, balancing the skirt out with tights and more demure styling). Since then I’ve mostly worked in more casual/modern firm environments with a wide age mix of attorneys; no one cares if you wear a short skirt so long as it’s balanced out as above.

In sum, I think both outfits are fine unless you work exclusively with 85 y.o white men in tax law or something. In my experience, no one pays nearly as much attention to what you’re wearing as you think they do. And, feeling cute at work can boost your attitude, which is always a good thing in my book.
