Super model oganwu takes nigerian fashion swiss runway #

I think there may be a few assumptions in your statement that need to be clarified!

Firstly, I'm assuming you're referring to a Nigerian supermodel named Oganwu who has walked the runway for a Swiss fashion brand. If that's the case, I'd be happy to help you with the information.

However, I'd like to clarify a few things:

1. Is Oganwu a real supermodel? If so, could you please provide more context or information about her?
2. Is there a specific Swiss fashion brand that Oganwu has walked the runway for? If so, which one?
3. Are you referring to a specific event or show that took place on the Swiss runway?

Once I have more information, I'd be happy to help you with your query!
