I decided to go through my insights on Instagram and all of my posts has as least 1 book mark. I can't see who did them.
Here's an example

its unsure to reasons why people would save pics on insta but I am sure they have there reasons, it doesn't look like it would be for the normal idea of wearing less. but I wouldn't worry about it atm. just keep an eye on it
