Thanks all!
You know, I do like chambray and pale grey pants too, for lighter neutrals, but those colors are well-represented in my tops.
I've had *bright* pink jeans in the past. The trouble with them, I found, is they're very seasonally specific -- I never wanted to wear them outside of spring. They were too warm to wear in summer.
Viva -- I think I tried those very same old school J Crew chinos last year, because they looked basically perfect, but on me the proportions were very off. Last year they came in a dark red/burgundy that was very tempting.
Rachylou -- I think, maybe, the first khaki (developed by the army methinks) actually did have an olive-y cast to it? I'll have to go dig up some history. Now I'm curious.
Style Fan -- I really like the mid-tone blue, too! I am waiting to try the Everlane wide legs in a very similar color, so if those fit, I'll be all set for french blue.
