Here's a possible design for a ClothingBrand class in Python:

```python
class ClothingBrand:
    def __init__(self, name, founder, year_founded, headquarters):
        self.name = name
        self.founder = founder
        self.year_founded = year_founded
        self.headquarters = headquarters
        self.products = []
        
    def add_product(self, product):
        self.products.append(product)
        
    def remove_product(self, product):
        if product in self.products:
            self.products.remove(product)
        
    def get_products(self):
        return self.products
```

This class has four attributes representing the brand's name, founder, year founded, and headquarters. It also has a list of products that can be added or removed with the add_product and remove_product methods, respectively. Finally, the get_products method returns the list of products. This is just one possible implementation, and depending on the specific requirements of the program, there may be additional methods or attributes needed.
