Petite Skinny Jeans – Best Price!

Ive always wanted a different colored jean other than blue.
Everyone I know has black but Ive always admired white.
So I have 3 questions:
1.Does skinny white look good on or is just boot cut white look better?

2. Which one will I get more use out of, Black or white?

3. Are Urban outfiter jeans comfortable? Do they fit alright? Anyone who has some that can tell me?
These are the 2 jeans Im looking at:

Im very petite, 5 5” and still growing and I look alright in skinny jeans (I have some). If you could give me advice, recomendations, etc. it would be appreciated with extra 10 points. thx.
Yea I do have a lot of bright colored shirts to work with..

for my sister’s 14th birthday, I am getting her skinny jeans. she really wants skinny jeans that are red, pink, blue, purple, whatever.

She is a size 14 kids and is pretty skinny and petite.
She is 5′1” and weights probably about 85 to 87 pounds.
She got pink skinny jeans from forever 21 and they were a 27, and they were too big. (not by too much, but enough that she didn’t like them)

so, i am really confused by the sizes at Forever 21!!!
i really want to get her this pair, so what size would she be?
