Here are a few of the items I have found at mainstream chain stores:
|Cracker Barrel Store (restaurant)|
|Belk Department Store|
Target is a trendier superstore, so they bought into the "edgy" trend. This being said, target stocks some lovely boots and heels. They also carry lacy items, skinny jeans, pinstriped items, etc.
Forever 21 is another store that stocks up on items with a darker aesthetic. This store affordable as far as mall prices go. I've seen all sorts of items there. Many flowy sheer pieces, interesting jewelry, and I even saw a motorcycle dress.
H&M: It's not as affordable as Forever 21, but it's more high fashion I suppose. I purchased high-waisted long black skirt from this store. They also carry a line inspired by The Girl With The Dragon Tattoo. I've also spotted velvet gloves and a mini top hat headband.
Lastly, Claire's. Claire's is a store geared for pre-teens. It has a lot of cheap quality stuff, but I still love it. More recently, they've been stocking leather boots, Nightmare Before Christmas merchandise, hosiery, and so many gloves and armwarmers. I've been going to this place since I was little, and I don't see myself stopping.
There you have it, folks. Don't overlook mainstream stores. You don't know what you might find.
