the navy pinstripe is from jcrew ludlow, like this one:

although mine is from last yr, one center vent.
i would say the navy is very dark in person, the stripes are subtle. i guess it's a pretty standard jcrew navy suit that doesn't change much from yr to yr, so you'll know the color if you are familiar with jcrew.
i was confident that it would be appropriate for a legal interview in SF, until i read this thread.
although the bay area is pretty casual - lawyers wear just shirts and dress pants for work. a tie is rarely needed.
I hear the weather in SF has been pretty cool lately so you might be able to go with the flannel, but I also think if you keep the rest of your outfit toned down the jcrew suit will be totally fine.
