Hi!
I understand you need a person with good knowledge in fashion and what's important in a fashion blog to accomplish your project.
I'm from Brazil, had my own fashion brand and had already done this kind of task more than once. I'm a very good online researcher and I know exactly how to search for these bloggers.
Just let me know the exact style of fashion blogger you need (street style, inspirational, look of the day, etc.) and I'll give you the 40-50 blogs you need.
If you have any questions please let me know.
Best regards,
Juliana
