Loooooove this sweater
I ordered both colors, but ended up keeping the green in petite xs b/c the red in xs was just slightly too big. both colors are gorgeous, and i agree they have a retro 70's vibe. just a tad itchy, but not enough that it would make an undershirt absolutely necessary. i'll probably just wear it alone. i think the regular size would work for most petites b/c it's not ridiculously long. i would suggest sizing down in regular if you're petite though: for instance, the regular xs fit noticeably larger
