It works, but you just have to wear it all the time. You have to learn to transfer the fat under your armpits to the cups. Fat has the function of transfer. Underwear is like a mold, and your figure is what you wear. Massage the breast every day: 1, insert the left hand into the waist, and merge the four fingers of the right hand into the left armpit. 2. Press and push with your thumb in a fan shape from top to bottom, left and right 10 times. When massaging, the muscles in the armpit and chest will feel sore, because the armpit is the part with the most lymph glands. This action can massage lymph, eliminate accessory milk and promote detoxification metabolism.
