Inspiration: Jessica Alba
This style is so simple, casual, and cute! But above all, it's easy and cheap! You can find a similar cardigan at Urban Outfitters for only $39 and you will get a lot of use out of it or Target has an even cheaper version of it for $20 (just not in Navy Blue). Knowing Jessica Alba and her love of skinny jeans, I'm betting that is what she is wearing. Old Navy sells some for $29.50 and they last forever!
As for the accessories, which totally make this outfit, I found similar funky sunglasses at Unique Vintage for only $12, and a beautiful royal blue scarf on Etsy for a mere $10!
So there you go Mommies, a cute, fashionable and budget savvy outfit!
