Makeup does help some women getting more attention from males when it is well used, please don't be like those celebrities that wear tons of makeup and without it they're the worst thing you can ever imagine.
If you used to be obese you may lack some self-esteem, but you say you're thinner and more attractive, still, if you work with hotter females you may not get hit as many times you would like by males, or not at all, because your beauty may not surface if other females around you wear the same "tricks".
Men tend to look to those that are prettier. It's cheating, but yes, we men fell for it in ages.
"E ao imenso e possível oceano
Ensinam estas Quinas, que aqui vês,
Que o mar com fim será grego ou romano:
O mar sem fim é português."
