I bought this sports bra for mainly working out, but ended up wearing it for my job (in security). Because I walk around a lot at work, and at times have to chase someone, this bra definitely holds up to expectations. I am very excited to have one as I would definitely recommend it to anyone who likes to go either jogging or running. I am also a fairly large breasted woman and bought the 2x, more than enough room to "breathe" so to speak. It's form fitting and perfect for what I need it to do. Highly recommended.
