ChantelleWomen's C Essential Full Coverage Smooth Bra, Ultra Nude, 34DD/E

Why is it squeaking? Has this been fixed? Want to buy it but..,,

How wide is the band on the 32C bra? How many hooks are in each column? 1, 2 or 3. I don't like the ones with a narrow band and one hook

Are the straps fully adjustable?
