Review (5/5): Simple and effective. Not the most comfortable under clothes. My cat also LOVES it!
[[VIDEOID:1092bc81f2964549f15d5d38061471fc]] It is definitely well designed, effective and comfortable over clothes. Under clothes isn't ideal if you plan on moving a lot. The size is pretty perfect, though I'm rather small (28" waist) so it was an inch or two too small to be perfect for me, but it sure did the job.
Also, my cat probably loves it more than I do! But clearly in the video, she struggles to put it on... Would recommend for cats.
