This slip is from Free People, who have become my go to for fall clothing! So easy to layer all their pieces. They're expensive but you can find a lot of used pieces on eBay for about 50% off!
The boots are from Jeffrey Campbell and Free People. Such a good investment! They go with Everything! I highly recommend these if you want a pair of boots that you can wear everyday. They're pricey but well worth it in my opinion.

Boots: (has a narrow fit so size up if needed, best to size up if between sizes) http://www.freepeople.com/shop/Joe-Lace-Up-Boot/?productOptionIDs=0B6E9CAD-A8F4-4CCF-8A37-466219F4EA95&cm_mmc=CA_PLAUS-_-Google+PLA-_-PLA-_-904311&source=PLA&CAWELAID=120120800000000220&source=PLA&catargetid=120120800000498967&cadevice=m&gclid=CLfghqnDz8kCFQ8zaQodhWMKBg
