True to size; back has four rows of hooks and the band was wide enough to hold the girls in during strenuous activity. The material is super comfortable while being firm enough for high impact exercises like running. This bra is the answer to every need a busty gal looking to get active has! I would buy it again and again and again! The colour is also sporty and does not look like a maternity bra (this happens a lot when the cup sizes are big). I didn't need to struggle into a racerback overhead tank-style bra that other sports brands might have because it hooks at the back like a regular bra. No uniboob issues; I'm tempted to just use this as a regular bra, it is that comfortable. 10 stars if I could!
