That's a tough one. Both ones are majorly cute and have soooo much to look at! I like super colorful, very busy prints - so obviously I love both Foresta and Vacanze.
Forest has stronger colors, I think, with the greens and yellows and reds - and of course it has apples ALL over it, which I LOVE.
Vacanze is a super-spirited holiday print, but I can't see wearing it past February or March. I live in So. Cali, and we don't even see snow..
But, yeah. I'd STILL get both prints in EVERYTHING.
