This cardigan happens to be thrifted from my local Goodwill. So you could take your chances there or another thrift store and look for chunky cardigans. OR I found this one at Gap for $98.00 or this one from Target for $29.99.
The wine colored tee shirt is from Old Navy and it's priced for $5.00!!
The distressed skinny jeans are thrifted too. But I highly recommend the Universal Thread brand at Target.for $27.99! They are so comfy. This pair isn't quite as distressed as the ones in my photo but I think that's a better. Mine are almost too distressed.
The boots are Chelsea Crew but from a few years back. They don't have them on their website anymore. I found these on Amazon for $64.99. Or these cute ones from JC Penny on sale for $28. You could change the laces to olive green or a pretty burgundy...
The bag was a score I got on Ebay a few years back. I have no idea how I stumbled upon it. But I really fought it out with another bidder for this thing! There are quite a few on Etsy and the prices are a little on the higher side since they are made by hand. There are some on Ebay for a little bit lower. Just search for saddleback blanket purse or bag.
