I do not know if Wonderbra designs special support bra "amazon" lower quality but my sister's store bought is niquel while mine broke from first use! Indeed there are notches along the hat so I broke 3 on each cap ... ie unwearable ... I will try to sew up but it is not won ... Because of that I had to put 5 times in one year ... I who buys bras H & M in general ... I should have stayed at H & M ... I do not recommend it at all or so to buy the store!
