LZ Response:This is the first time LZ has received complaint for this bra. You might need a bigger band size (40A) for this style, it seems that 38A is too tight and that’s why it hurts you. Also, it could be that this bra is not good for your body shape, not every bra is for all customers. As you said, you own other LZ bra's that fit perfect on your body. amanda from buffalo
