I did buy this trench, Sveta! The sleeves were part of what made me choose it. They were nearly too long one me (good for you), and were roomy enough to layer, without that 80's big sleeve look. They give room while still looking tailored, if that makes sense.
The color is better than it looks in the photo, and the fabric is substantial, the stitching and construction is good for the price. I do with the waist were a tad bit longer. It would be possible, of course, to move the faux-leather guides for the belt down a bit.
I did get the extra large, because I needed it in the upper back and chest --- I suspect you would not need that extra space.
Hope that helps!
