You could say we have a soft spot for fashion start-ups at Refinery29. Humble beginnings, innovative ideas, passionate staffers, and (yes!) success. Sound familiar? We're taking a few well-deserved moments to give a standing ovation to our fellow fashion start-ups that are changing the way we shop, share inspiration, swap personal stories, and give back. Make no mistake, these bookmarked websites make weekly, if not daily, appearances in our browsers. Tapping into some of the creative minds behind these nine successful start-ups (AKA their founders), we've also corralled valuable advice — perfect for your own entrepreneurial endeavors someday!
