I have two of these bras and, while not perfect, they are the best sports bra for me. I have a very large natural bust and relatively small rib cage (32GG). I love this bra because it does not let my boobs move. I first purchased a size 2 and that worked well but I decided to get a size 1 for an even more secure fit. There is nothing, nothing, nothing sexy about this bra. It's ugly AF (shiny material) and it has visible seams but man does it do the job. It sucks that it's ugly because it shows in all of my work out tanks but I'll take an ugly bra and uniboob over being hesitant to do jumping jacks. I ran a 10 miler in this bra and I do all sorts of HIIT classes. Again, the material on this bra should really be improved. It is not moisture wicking or quick drying so you'll definitely want to get out of it as soon as you're done working out.
