For anyone who's looking to jump on the mustard/gold/ochre train, or in search of cotton-rich long sleeve layering tops, here's a good contender from Madewell. It's a silky cotton/hemp/viscose blend with a nice sheen. The ribbing has a great texture which, along with the lettuce edge sleeves, is very evocative of the 90s for me. I'd say it's true to size and the colour is pretty accurate on my screen. I took an XS and it is not too long (I find a lot of knit tops are too long on me, even for tucking in), does not bunch up at my hips or ride up on my waist. The sleeves are slim but not tight, great under jackets. I picked up the Naples Yellow, but am tempted to go back for the Onyx Heather if this one washes and wears well -- nice alternative to the classic ribbed black turtleneck for those who struggle with turtlenecks. (I also couldn't resist the tiger scarf and matching socks, so I think my fall mustard capsule is nearing completion!) I will post pics when I get a chance.
