On my last trip to China in December and in one of my favorite KTV's.  Picked two girls to sit at 200 RMB each, (yes it's much cheaper where I go).  Both were friendly and playable.  

Upon reaching inside to explore the treasures of one of them I find no bra and a very nice pair of breasts, nicely pointed (B or C), and no sag at all.  Kind of the pyramid type that I like.  As usual I am trying to find the nipple to give it a small tweak.  No luck--no nipple?  Playing around quite a bit more and drinking a bit more I find she has on pasties.  Sort of a small foam sticky pad that is about 1 or 2 inches in diameter (I know because I peeled it off).  Yes, there were nipples under there, but I really wonder why they were there or why she was wearing them?  Her clothes were somewhat loose and dark color and a hardened nipple would not have shown through them.

Now I know the Chinese girls will do weird things like wear glasses with no lens, but this was very new to me and has my curiosity aroused.  Playing around in the KTV, her panties were normal (as if that makes any difference), not Grandma, but not super sexy either.  I thought perhaps she had had a recent child and these could have been to stop leakage, but her body had no signs that I could see.  

Oh well, another unexplained Chinese phenomenon.

How old are you ?

She might have sensitive nipples that get irritated by her clothing. Usually that's only necessary if you're doing physical activity like running. Maybe she's been felt up before to the point of irritation and uses them as a precaution.

A lot older than you!  But it made me wonder.

I think if that were the case she would have been wearing a bra.

Maybe she finds bras uncomfortable. I dunno. You should have asked her instead of random men online.

This is very common in China when girls don't wear bras. They are not comfortable showing the nipples through their clothes. This is somewhat accepted in the West but a no-go for them. It is somewhat of a cultural thing, I guess.

those are called nipple tape some of them are made of silicone we make the models use them for photoshoots to hide there nipples

Exactly what they were!  Finally someone knows what I was talking about.  Still as bit curious why a KTV girl would wear them, her clothes were of the type that the nipples would not have shown anyway..  Not important enough to worry about though.

I still had a good time (alone) in the KTV with singing, drinking, and some light playing around.  I actually pulled one of the tapes off because I wanted to see it.  That night I sat two girls at 200 each.  One just to sit and the other with the option to take home.  The KTV's I go to let you know up front which ones are available for take out, some with a colored badge or ribbon tie, other times they just split them up.  If I am alone and decide to do a KTV, that is my preferred method.  Even sometimes take two go out but let them know you are only going to take one back.  Little competition can be fun!  Eventually decided to pass, the one I had picked to take back just didn't do it for me.  figured a good nights sleep was a better choice than going home with one I really didn't care for.

A friend of mine used to just ask when the girl's nipples were at attention: "Are you cold, or just horny ??"
