It all depends on the woman... like most things there is a full spectrum. Some are very aware of what can be seen at all times and may "accidentally" or intentionally show more depending on the situation. Others are some times aware and other times not, much seems to be driven by mood. And some seem to be oblivious much of the time and continually have "accidents" - years ago had a GF like that. Part of the fun is, after enjoying what may be on display, trying to determine the motivation for the show, if any.
