What is the difference between wearing makeup and and celebrating a birthday?

Most of the women mentioned in the Bible who wore makeup were prostitutes. Jehovah's Witnesses state that it is okay to wear a little makeup because the Bible does not say it is NOT allowed. According to Jehovah's Witnesses, there are two accounts of birthdays being celebrated in the Bible and both had to do with beheadings/murders. Pagans also celebrated birthdays. Because of those two reasons/IMPLICATIONS, celebrating birthdays is out of the question.

Same goes for wearing makeup. Pagan origins, prostitutes wearing makeup, vanity, decorating the face. For what purpose does painting the face serve in God's eyes YET it is ALLOWED?

I have nothing against wearing makeup but when hypocrites use the Bible to make weak implications based on weak biblical verses such as not celebrating birthdays because of negative association (murder), what should be said about wearing makeup?

1) Makeup=pagan=vanity BUT their teachings based on implications ALLOW the wearing of makeup.

2) Birthdays=pagan=associated with murder NOT ALLOWED based on once again implications.

Is makeup for SELF? Is it done to make SELF "get" more beauty, "get" more attention-and "get" more looks from others? Is painting the face done for purely SELFISH reasons?

What would be the difference between decorating a pagan tree and decorating the body?

I believe the argument the Jehovah's Witnesses pose on ALLOWING a woman to wear a little bit of makeup as part of proper grooming (even though it is associated with prostitutes & vanity) vs. not celebrating birthdays or certain holidays due to pagan origins or associating them with acts of murder IS redundant/hypocritical.
