I am a bit outdated with fashion and seek advice from you people here. I am trying to revisit jeans and shoes.

-Me having thin legs and cannot wear skinny jeans, are fitted bootcut or fitted straight jeans still considered 'in' or acceptable?
-How long should a pair of jeans be? ie. when I am standing, should the bottom of the leg touch the ground, past the ground, etc?
-Most jeans nowadays are low rise. How to wear them properly without giving myself a wedgie or have the feeling my pants are falling?
-What non-sneaker shoes would look good with jeans on a friday night outing?
-And what belts to go with the above?

TIA
