It is always difficult to judge aesthetics from a picture but the coat looks decent to me. While we all know that the quality is probably not the greatest, it probably wouldn't be too bad to wear with a decent suit. My advice is to try the coat on with a suit (because you should make sure it fits you decently over what you would wear it with), see if it is mostly wool (it says wool/nylon....if the nylon is more than half I would pass) and judge for yourself whether or not it works well. If you like the feel, and it doesnt look synthetic I say go for it. $70 is pretty cheap.
I took a look at it over lunch and it was 80 wool/20 nylon. The charcoal color base color was nice, but the blend almost makes it look a bit linty as there are white fibers on top of the charcoal base. Didn't have my size (38 too small, 42 too big) so I ordered the 40. I also ordered a HSM from Amazon for a few buck more ($104) and will compare the two when they arrive and keep the one I like better.
