I love the Western-inspired look. It's a very "in" look right now and is easy to do. This particular look is inspired by the colors purple and turquoise.
You can create a Western look with a flowery, light sundress and cowgirl boots. They have a great selection of sundresses from Forever 21 that are inexpensive. The cowgirl boots can be found online as well. You can go for a colored boot like the ones in the picture or you can get neural colored boots that match all different kinds of outfits. Either way you go, it'll look great!
Accessories can be found all over the place. Go for big jewels with a lot of details.
If you have any ideas to perfect this look, comment and share! Get creative with it and have fun :)
