Target has some really similar ones here you can check out locally and try on before buying. I saw them this weekend, and they look much better in person than online. They have them in black or brown as well.
Recently, I've really been on a kick about feminine outfits with tough accents (see Zoe Saldana and Ashley Tisdale Celeb Inspiration posts). I think it's such a fun, sexy way to style outfits and I'm hoping to just pick up some key pieces to mix into my wardrobe.
Have you bought any boots for fall? What styles are you shopping for?
