I just ordered/received this full length trenchcoat, and although the fit is not right for me, it's a REALLY nice coat, so maybe someone else might like to try it.  I love the plaid pattern and the fact that it's single breasted.

I got it in a medium regular. The hem and sleeves are too long, which is alterable, but the cut is overall a bit too slim for me. I need to be able to close coats and drive in them and this one is too snug for that. Sizing up would make the shoulders too big etc. The coat does not seem to be available in a petite size - I checked a number of places including a google search. So, sadly, it’s going back,

The same print comes in a cropped version, double breasted, that does come in petite sizes, but i just bought a cropped trench in a solid darkish brown and this would be too similar (I think - still mulling it). 

The plaid is a medium brown, soft black, and cream/beige. Really nice buckles on all the belts, etc. The hood ion the full length coat is enormous but easily removable (zipper). It's not water resistant.

All the variations are on sale at Macys right now. 

A warmish neutral small pattern plaid coat in a petite size seems a real unicorn!   

FInds: 

• the long coat
• the short one - two separate finds for the regular size and petite size
• the solid brown one I found ago at TJmaxx in mid-Feb; brand is house of harlow; not a petite size but works surprisingly
