Blue suit with rope stripe acceptable for a legal interview?

If there is sufficient doubt that you have to ask the question, then don't wear it for interviews.

Probably but you do not tell us anything about yourself. Were you a young graduate, were you to be 50 yo then different considerations would apply.

Picture of suit?

Solid's are better IMO.

Yes. You're fine. If it helps, I'm on the hiring committee of a very large firm.

Conservative-nothing too flashy (avoid the diamond studded rolex). If what you are wearing makes you feel uncomfortable, don't wear it.

Be sure to wear it with a solid white shirt and a simple tie and you should be fine.

You're fine with that suit and a simple white shirt and conservative tie. In my interviews, I'm looking for someone who will fit in, which means basic in our firm (although I am somewhat out there, but I've been out of school for 20 years.) Your task is to research the firm and see what kind of stuff they do. What is conservative for a large firm may not fit with a small firm, say 2-3 lawyers. When in doubt, just keep it simple; blue suit, white shirt, striped/regimental tie in basic color groups, blue/red/gold. If you're in the reasonable zone, you'll be fine. Now, on to more important things, you can concentrate on whether you have the legal skills they are looking for. Good luck.

Any interest in hiring a judicial clerk from Houston?

I worked at Milbank for 6 years and interviewed no less than 150 law students during that time. NOBODY is going to care about the suit you're wearing unless you're wearing something a clown would wear.

Trust me, I could care less if you wore blue/black/charcoal. "If" I remember you, it's either because you were able to engage me as a person in conversation or because you're a complete social reject that I can't wait to go tell everyone about.

Aim for the former.

Agreed. Just do your homework on the people who are interviewing you and have a few good questions canned.
