This is the only bra that I can wear that the straps stay up on.  Its because of the T-back.  They do show under some scoop neck tops so I have to pin them up, but nothing is worse than fighting bra straps all day every day.  So if you are like me and have never found a bra that straps stay up on (I have what they call sloping shoulders) then try this bra.  It is also made of very soft comfortable material.  Eventually after several years, the underwire breaks and I have to toss them, but I'd say they last 5+ years and are wore out before that happens.  I never dry them in the dryer, I always hang dry them too, that makes them last longer.
LOVE THIS BRA.
