If you are only receiving around 50 visitors per day, you'll definitely won't make a lot from Google AdSense.
I suggest that you join a CPA Network and promote offers that are related to fashion.
The pay is good for every conversion. Even if you're only receiving a small amount of traffic as long as you convert that traffic, you'll make good money.
So that's it try monetizing your fashion blog with a popular CPA Network and see what happens.
