hi, thanks for your replies.. i will make it more clear.

i want to find a solution on how i can make a clothe/fabric heavy. (putting some chemicals or likewise), then i will do it in wrist bands and leg bands, in that case no one will notice that im wearing a wrist/ankle weights. i want to put it in wrist bands so that my attire will not be ridiculous. because using those wrist/ankle weights that you can buy, is big enough to be notice.
