i see nothing wrong with it. society has trained us to think that women with hair anywhere are gross/unattractive. Some people may adhere to that belief, but not all. More and more women these days are shaving less. If a woman does not want to shave her underarms, then thats her right. if you don't like it... don't look at it..
I don't see anything wrong with it. This obsession with hairlessness is annoying anyways. My friend is Chinese and she never shaves her underarms. At first I thought it was weird, but it's not like it makes her any less attractive, it's just what the media tells us what is normal
His thought behind is complete cr*p but I don't mind his "art". The ideal that a woman should not be overly hairy is as old as humanity. Already the ancient Sumerians wrote about it: Beside a bunch of religous texts, they left us one of a noble woman explaining how to get rid of hairs anywhere. In Greek it was also the ideal for young men (with no white hair). Hair belonged to the head and nowhere else. For older men it was interestingly normal to wear a beard (as in Herodot's history mentioned: after the hair started growing white). For the ancient Germans it was about the same. A woman would wear hair on her head and nowhere else (they used some mixture of bee wax and tar for their "brazilian" waxing and honey for treating the skin afterwards).
The question of what body shape looks good, has changed a lot during history. From "normal" in Ancient Greek (I don't know earlier cultures though) to very thin in Ancient Rome to chubby during the Medieval to obese in 17th to 19th century back to first "normal" and then extremely thin again. Now it's swaying back to a more normal.
