This recreation might not necessarily be cheaper but it is available...unlike the Alice + Olivia look which is currently sold out.
I found these pants at Madewell and I am loving them.
I found this one shouldered top at Banana Republic. You can always count on Banana Republic to have cute basics that are also great quality.
Tuck this top in to achieve the same look at the Alice + Oliva outfit. Super cute, right??
