JB 3 I was tempted to give it 5 star because the product came with a leaflet saying that I’ll get an 800 JPY gift card if I do so.But, nah, here instead is an honest review.It does feel like it gives posture support. It gently pulls back the shoulders. But it doesn’t shape the arms, as promised. I’ve seen better alternatives on Amazon for cheaper price.Most importantly, it’s a bit painful around the chest. (Ladies, breast cancer is a real threat. Take care of your chests please.) Given this last bit, it’s shocking that this product is not eligible for returns.I’d recommend it ONLY if you have 1700 JPY to burn because (as with any apparel bought online) it’s a hit-and-miss. Much depends on whether the thing fits your own unique physique.
