She's a "modern" woman/model ^^^
She has a face women like and men want to ___________________ on and do things to
She has enough meat for some to say she can be "thicc" and enough meat to also be skinny
Her chest is rather cute and perky for those who don't want a big chest, and her booty she works on it.
Her skin looks rather soft, her eye colour is wonderful and she knows what do to with her hair.
She's younger than she looks with so many men wanting that younger looking girl that's legal age.
Aside from a looks thing, she seems down to earth, an admitted introvert which a ton of society can relate to and see that if she can do all these things and still be an introvert there's no reason they can't. She can model, people who enjoy looking at pure fashion not just fake VS fashion really like Taylor and she can do her HF stuff, model wanna be sexy things for VS AND then go do a goofy VS Pink shoot or a goofy magazine shoot and not look out of place. She's your swiss army knife your jack of all trades, not exceptional at anything but really strong really good at everything, so her appeal is very big to anyone looking for a great model, a fun younger woman and someone (depending on taste) who can be downright sexy.
I'm not a Taylor fan anymore, she doesn't do much for me (Personal preference) but from what I've seen and heard from her fans that's a lot of it, plus personal input.
