Specifically, my wife likes to wear tops that are very open at the neck (the collar lying somewhere on her shoulders), but she doesn’t particularly want bra straps all over the place. She is not averse to a teeny amount of cleavage but her main concern is to be able to wear such tops without bra straps showing.
So. What is a good sort of bra to buy her? Neither of us has any idea. I’ve done a bit of Google-shopping for “strapless bras” (haven’t we all) but was instantly buried beneath more different kinds of bosom-containers than I could ever have dreamed existed. If you people have favourites, for comfort and ease of use and price, that’d be groovy.
