I might be too late to this thread, but I bought a similar trench from ON a couple years ago. It's a bright magenta and I love the color, BUT
1. It doesn't look well-made (not cheap per se, but just not wow!)
2. Mine doesn't have the tab sleeves, but the sleeve hems kept getting folded over in wierd ways, so I ended up having to stich them down to keep them from shifting.
3. The belt isn't stiff enough, so if you tie it it gets horribly folded and creased.
In hindsight, I probably should have bought a better-made trench even if it wasn't in a fun color. It was the color that sold me. I still use it, but rarely.
Having said all that, given that you have rewards and it would be v. cheap you might still want to go for it.
I *love* the green color!
