How much should I put into ads for a clothing group?

Ok, so I’m planning on opening up a clothing group. I’m on a tight budget of around 1.4k, would that be enough to advertise a clothing group and earn profit in return? (I plan on hiring designers also, but they would be payed differently)

I wonder if directly advertising an outfit would be more beneficial. (the ad showing the outfit of course). I would definitely try a test run first.

How much, if I would, do you think I should spend on the test run?
