I read a bunch of reviews before I purchased this item, and it was subsequently exactly what I was expecting.  Yes, it is not the best quality, but it serves its purpose perfectly (purr-pose purr-fectly?).  The mask, belt, and ears were great (cheap, but again, what I was expecting - they worked just fine).

It is definitely true that the gloves do not overlap the sleeves, so if you want a streamlined look with your whole arms covered, you'll have to pick up a longer pair of gloves.

I'm 5'8 and 135 pounds and got the medium - it was a bit loose-ish around my midsection/upper legs but still fit pretty tight and I felt sexy in it.  I couldn't have gone down to a small because my legs are too long - but no need, it probably would have looked awkward if I'd tried anyway.

I would definitely recommend it!
