Actually if I was in the niche of fashion I would do it without using a generic image that is on Amazon.
Here is what I would do.
Keyword: Leather Pencil Skirt
Your image
The image I would use.
Which image do you find more eye popping?
I would search popular fashion on Google, find a image like the one above and build my blog post around that image.
Post to Pinterest and use a description like: Just got a new Leather Pencil Skirt to go out for drinks with my friends.
Something simple like that and you will get really good traffic.You look like a real person and you have a leg up on 75% of the other fashion niche marketers that are posting generic images.
