Hi there! So sorry for your experience and completely understand your frustration with sizing - if you are a 28G, I would suggest ordering this correct size. We don't carry it in the Spacer Balconette as of yet but we do have it in the fuller coverage sister, the Sublime Spacer Bra, which will offer you more coverage and a better fit. If you want to stick to the Spacer Balconette, a 30E compared to your 28G calculated size would make sense why you don't feel covered as your cups may fit way too small. A 30F would be a better fit for you for the Spacer Balconette as it's a closer sister size to 28G.
