Judging by my height and weight, can I fit into size 3 jeans? How a out a size 1? Please help me!?

I'm doing some online shopping and I don't know what size skinny jeans to buy.

I'm 5'7 and weight 118 lbs. Do you think I can fit into a size 3? How about a size 1? Will it be too small if I buy it? And will it hurt and be uncomfortable?

Thank you.
