Example Input: My 4-year old girl loved the costume but unfortunately it did not include the mask. I inquired the seller and they confirmed there was a confusion : the description of the Costume did not include a mask , I replied even I did not notice it in the description, the picture showed the girl with the mask and there was no clarification about it. I think they should have made a clarification, it seems to me it is false publicity. It is good to know they have updated the picture.
Example Output: Positive

Example Input: I enjoy this book very much. It is a timely classic with which I am happy to now have my own copy.
Example Output: Positive

Example Input: So I just got mine today and I put it on right out of the box. Like some have said, takes a few minutes to get used to it. I've been wearing it for 5 hours now and I just love it. It covers everything that needs to be covered (and I am long-waisted). It stays put, which I love. It's comfortable. It makes my waist look great and flattens my stomach "pooch". It's comfortable enough to sit in. Best of all, instant posture makeover and it is easing my lower back pain by providing support. I'm looking forward to wearing this for a long time and already foresee a black one in my future. I wonder if I can wear it on my runs? Hmmm... Also: I have a size 31 inch waist and the medium fits perfect on the first loops. Just take your measurements before you order. Hopefully, as I lose weight (from my running/training program) I can cinch it to the tighter loops and get a little more use out of it. Well... then I'll just have to get a size small! I love it!
