What is the Korean alternative to Uniqlo?

Could you tell me, in your opinion, what the most popular Korean clothing retailer is that offers a similar range of products and pricing to the Japanese brand Uniqlo? I'm particularly interested in knowing if there's a Korean alternative that's widely recognized for its affordable yet stylish clothing options, similar to how Uniqlo has become a go-to for many consumers worldwide. Is there a specific Korean brand that stands out as a comparable choice for those seeking similar fashion and quality, but with a local twist?
