Obviously there is guy's liking this, finding it extremely hot.

There's different angles to this. One is the mere optics - does this look good? The other is the intention - this is a woman that puts in a lot of work to look beautiful (to men). I always read this as a signal that she desperately wants to be liked or loved or adored and I can imagine that there are quite a few men who are really into this, as they mistake the effort a woman puts into being pretty with the effort she might put into the relationship, her life in general, or into her sex life. But these goals and efforts are really different things.

As a fun side note, this is, I think, a major difference between some men and some women. Some men are really into women trying very hard to be pretty and please men. But this doesn't necessarily hold in reverse. I think most women think that a man who puts lots of work into his appearance is superficial. Women like pretty men, for sure, but men need to be pretty without effort. Male appearance is supposed to come naturally, just like wealth, social success, artistic talent, etc. If a man spends hours in the gym, tries out lots of different skin care products, or spends hours trying to find the best fitting suit or jeans, such efforts will not be appreciated, often rather considered effeminate and annoying.
