I think it's possible to be skinny AND curvy! However, if it were skinny and non-curvy vs a little pudgy and curvy I'd go with the latter on most days. Have you ever noticed how your opinions change on different days, though? Like, sometimes I'll see a girl whose curvy look awesome in an outfit and want to be like her. Other times, I'll see a skinny girl look great and want to be like her. About 2 months ago, I started to eat much more in an attempt to gain weight and it worked! 8 pounds in about 1 month. However, it was really hard to point out where the fat had gone, until my brother commented (and kept going on) about how my legs looked all fat and like lady-ish. Eating so much was just hard, though. Forcing yourself to constantly eat and never being truly hungry because you're always eating is not enjoyable and totally not worth it to gain weight.
But yeah, curvy all the way!
