Best Petite Brands

I’m in my early 40’s and struggling to find petite-friendly brands that I love. I am self-employed and mostly work from home, but we are getting ready to do some business traveling and I desperately need business casual clothing that doesn’t make me look like a frumpy mess. Honestly, I need an entire wardrobe overhaul, so I’m trying to slowly add great pieces a little at a time. I gained some weight after turning 40 and my body shape completely changed over the past year or so; I have had to replace every piece of clothing I had. If you were starting from scratch in your wardrobe, where would you begin?
