imagining the beautiful

i am not able to co-relate the tools with the platform. i mean why do females look more beautiful when they beautify them. or how do our mind interpret something as beautiful. or why do a female looks more attractive when she applies an eye-liner or wear something that accentuates her fullness. today i saw two females who i see virtually daily and one of whom i find not beautiful but modern but she has a great [hourglass] body and another who i think is better looking and has a nice [full] body. now the former of them had a lace thong on today and the latter one skin tight indian top. the former managed to make an impression which she hasn't managed to till date and the latter impressed all the more. thus am trying to understand the role of the tools, the respective cloth they were wearing. or is it just the mind imagining?
