Im going to a picnic what to wear?

Well the jeans are a great idea! I hate when it's cold out and I see little tiny girls freezing in their short shorts and tank tops. You have 2 options, the way I see it. You can wear jeans and cute sneakers and then a comfy t-shirt like the looser ones, with a cami under it. Or you can try to be cuter about it and wear a fitted t-shirt and flats. It depends on how active you're going to be. I love a colorful v-neck with a different colored tank under it. Have fun! :)
