I agree with Bilby...those bras do not look supportive enough for anyone with larger breasts. You need to have more support, so you won't bounce.
I used to wear a Dcup...now I am barely a C. Sometimes aging plays dirty little tricks on you!
I wear Just MY Size bras..and they seem to work for me.
To keep the elastic in great shape..hang them to dry.
