What about unbuttoned, but tied at the waist over one of your bright dresses-like green or cobalt? Basically like a softer version of a denim jacket.

I like the untucked look with the shirt !

Chambrays are perfect layering pieces when the autumn starts to kick in with a T-shirt or turtleneck underneath and/or a sweater over the top

This is much more casual than we are used to seeing on you. How about wearing it out and tied with utility pants, maybe olive?

I think it looks great on you untucked.

I was going to suggest the JCrew sleeve roll as well. If that is too tight on you, then "roll" it by folding the cuffs over neatly twice, like in RunCarla's first pic. I don't think the scrunch suits your level of polish.

I'd wear it with the black or olive pants. It would probably work with a tube skirt too, but for me that's a bridge too far.

Do you do costume jewellery? I've seen outfits on Pinterest where several strings of bright chunky beads are layered over a denim or chambray shirt. I could see that working for you.

I like chambray shirts tied at the waist and with sleeves either scrunched or rolled.

I would try rolling the sleeves (scrunched never seems to stay in place for me at least anyway) and tying at the waist over a tee and skirt (or dress), column-of-color style, like suntiger says, almost like a lightweight topper treatment. Tying at the waist and rolling the sleeves helps give it structure. This is definitely a more casual, relaxed piece than we normally see for you, so it is a departure. But I think if you embrace the juxtaposition of this shirt with a dressier piece like a dress or skirt, and add casual shoes (and I like the idea of something more substantial like the oxfords), it could work. How about a statement necklace in the neckline too?

I like chambray shirts and am always drawn to them, but have given a couple away because I find myself not reaching for them much. Too warm in our summers here, and when it cools, I'm eager to wear other more substantial pieces. But I keep one around for the occasional time I'm in the mood to wear it. I think this piece will just need a little experimenting for you to find the look that really captures the way *you* want to wear it.

I missed this post yesterday, but wanted to say, yay for you for trying to remix a 2013 piece! It really reminds me of what I have been doing with the July challenge. I also found I could remix some things like my 2000 cardigan and 2011 skirt and end up enjoying them again. Mine had been sidelined for some years as well.
I like the sleeves up on it better on you. It looks awesome with the plaid pants. Will comment on the other post too.
