The first set is one from my Express x You collection. This is my favorite piece of the season and is made out of the most luxurious cashmere! What I love most about it is the versatility it has it can be worn both indoors and out. This set was also a November favorite.
A couple other places who I've discovered have amazing loungewear are Abercrombie&Fitch, Zara, & Other Stories
Unfortunately Zara doesn't allow affiliate links however I love them so much and feel like you all would love them as well. I have linked the top here and the bottoms here. The set from abercrombie is part of their Soft & Sexy collection and it is exactly that! These are the bits from them and from Stories :
