Do I have tubular breasts? Advice?

You appear to have very pretty slightly asymmetric breasts with some areolar protrusion but your breasts do not appear to be tubular. Once you have reached your target weight , if you still feel that your would be happier with a larger fuller breast size, an evaluation by a board certified plastic surgeon would be advisable to discuss all of your options. Sometimes the protruding subearoelar appearance can improve with augmentation, but if not, a correction can be undertaken at the same time with a resulting scar around the areola. It is a skin tightening operation which would fall under the general category of "mastopexy" or "breast lift", although your breasts do not need to be "lifted", just tightened to correct the protrusion. Best of luck to you.

Thank you for sharing your question and photographs. You do not have tuberous breasts and if you consider your breast size to be small, an augmentation with implants would be a good option.
