I love the top and the cardi:)
I can't tell if you're wearing leggings or skinnies but I think skinnies would look better and flats would be better! or a pair short black boots! :)
Honestly, you could do black OR grey boots with this outfit. All neutrals work together. Black,grey, brown. The light pink ruffle shirt gives it a pop of color, and some visual detail. Very cute!
Their jeans. I have black Uggs (sorry ugg haters haha) and i have black leather boots but they have a little bit off a heel on them. I guess they could work but not ideal.
