Is this a good company name?

You are developing the "Branding" for your enterprise. Consider that for whatever name you use, you must embed it into your customers awareness. Your name is ok because you tell us that you're selling clothing. The DUBii just tells me that I never heard it before. But does it mean anything to your market? If so; great! Otherwise you need to connect the name to customers. Spend some money on market research, focus groups, etc. Logo is good? Type styles, color, layout are key. Good Luck
