Very supportive without being too tight. I can wear this all day at work and not even realize it's on. I feel better than not wearing any bra at all, but it doesn't feel like one is on if you know what i mean. The straps do stick out under a tight shirt but its not that big of deal. I haven't had any trouble with the velcro coming off sporadically. They stay put even on a 25-mile backpacking trip!
