First tip is, don’t just put your logo on a blank piece of clothing. Instead first focus on creating the clothing piece then worry about the design after.
Second tip is, do not post more than once a day. A lot of people say post two to three times a day but doing that will lower your view, one time a day is the best amount
Third tip is to make something unique on your clothing piece, so if someone sees someone wearing it , they will notice it’s from your brand, an example of this is a nike tech. If you see the jacket without the logo you will still think of a nike tech just because of the look of it
And the last tip is do giveaways but in creative ways. Giveaways are a good way to market if you do them correctly and you can easily grow your brand with it.
