“The clothes were inspired by African motifs.” ~McCurry
To me the word inspiration is tied to respect. To be inspired by something is to love that thing so much, your love for it sparks a new creation. When you are inspired,you are awed by your muse, you want to learn more about your muse. Unless of course, your muse is Africa.
In your text, treat Africa as if it were one country. It is hot and dusty with rolling grasslands and huge herds of animals and tall, thin people who are starving. Or it is hot and steamy with very short people who eat primates. Don’t get bogged down with precise descriptions.
