Do I have tubular or just saggy breasts? What would be the best procedure to fix this issue? (Photos)

If you like your size and want to be round and perky, then a mastopexy will do that. If you want to be larger, then an implant alone will fill you out.
Good luck,

Thank
you very much for your question and photographs. From your pictures, it does
appear that you may have mildly tuberous breasts, with some ptosis or sagging.
You should be able to see dramatic results with a breast augmentation and lift
procedures. I recommend scheduling an in-person consultation with an
experienced, board certified plastic surgeon. He/she will examine your breast
and determine the best procedure or set of techniques to raise your breasts and
achieve the desired results.

From the photographs it looks as though you indeed have a modest amount of constriction of the base of the breast. Almost always the skin be corrected with breast augmentation if you're in the market for larger breasts. There are some measurements that need to be taken to substantiate this opinion based on photographs alone.
