I think it works both ways.
I suppose it's true that men in some way define what we perceive to be attractive, but I also reject this idea because it's been shown many times that women's magazines and the fashion industry promote skinny, thin androgynous women as the goal of most women. However, many heterosexual men will admit to preferring curvy or more natural looking women. So I wonder if originally, yes, women's idea of being attractive was a male costruct, but now as we have more freedom and power, if we are also to blame for our own self image.
Class issues also have a lot to contribute to ideas of beauty. In Elizabethan Europe (and in other areas) it was considered beautiful to be very pale because the working class had to work on the land and were therefore more likely to be tanned and/or weather-beaten, whereas aristocratic woman (and men) were pale because they did not need to go outside to work.
Similarly, in the Renaissance period, women were generally deemed attractive when they were full-bodied and fertile-looking. This again could be attributed to class as only the rich or aristocracy had the ability to feed themselves to such an extent.
Nowadays, we've done a reversal, where poor people can fill themselves up on fatty food with little nutrition, but rich people can afford personal trainers and dietitians and personal chefs. Or on a less extreme level, wealthier people (with usually, but not always, better access to education) tend to be able to choose healthier options more easily than poorer people.
People also tend to travel more (not the norm in Elizabethan - Victorian times) making tanned skin more popular, especially as rich people can afford to travel more in general. It's commonly held that Coco Chanel was one of the first major "celebrities" to promote tanned skin as a positive. Previous to the 20th century, tanning was considered lower class which is in correlation with the fact that people traveled less.
As for high heels it all depends on your outlook. High heeled shoes have been regularly called as a form of bondage, keeping women helpless, but then on the other end, you might say they make women taller than most men and I'd assume that if it came down to it, most people would rather be kicked by a flat shoe than a spiky stiletto heel.
I think that there are some women, yes, who become defined by their sexual attractiveness to men, but I also think that some women, like myself, choose to wear relatively revealing clothing without assuming we're screaming rape me to every man passing by. Surely the whole point of being a feminist is that you should feel comfortable with what you wear regardless of the male perspective?
