hi..large contoured cups have a curve at base that is according to body wall so they fit better..specially if u r a small frame u shdnt even think of anythng other than contoured cups..i ll suggest airlocks too bcz it is hard to put both cups together..air lock allow u to attach them to chest one by one and ofcourse u can pump n hold or snoogle a lot more easier
i dont know about foam rings
welcome to the family❤have faith in this system bcz it WORKS...in 3 months max u ll have VISIBLE OBVIOUS growth and then..it never stops to grow ❤ i just finished my 3 months n for tje 1st time in life i know what is a tight bra..my loose As are tight now so this is best thing u can do for urslf❤
i went off the topic..sorry for that..i really wanted to encourage u bcz at start we all need reassurance
