Yeah, there are only certain situations where this looks good and I must agree about these nice looking bras out there... ;)

I'm with Molfan...it all depends. Some women can pull it off, so long as the top isn't a sheer material because they are small enough that it's not tacky. I have seen plenty of women in denial about looking good braless, and it isn't pretty.

for the most part no. unless a woman is very small busted this does not look so good. it appears tacky especially a large busted woman or if you are wearing a thinner material shirt.especially if it is something you can see through. and yes I have seen women go braless with that kind of top.

Speaking from a resolutely male perspective, this can be quite charming, or utterly appalling.

if she has small breast and just a hint of nip

Unless the woman is an A cup, it just looks dumpy and unattractive. A little lift and separate is always better.

Not a glamorous way to run around.

No bones in the breasts so unless us ladies want a man singing to our chests: "Do your boobs hang low? Do they wobble too and fro? Can you tie them into a knot? Can you tie....."

Bouncy, bouncy.
