Capsule wardrobe brands?

This is my first time trying to revamp my wardrobe. I'm almost 30, had a baby a year ago and my current closet is just a mess of flannels, western wear, black dresses and some sad attempts at preppy/stylish. I'm really drawn toward eastern/southern style and would love my clothes to be all neutrals that I can dress up with fun accessories. I haven't shopped in so long, I don't even know where to start. How did you find your favorite capsule brands/guides? I dread shopping because I'm so bad at it... I'd love your favorite (reasonably affordable) brands!
