I'm sure you've heard – Instagram is all about creating your very own aesthetic.
Hootsuite said, "Your Instagram aesthetic is the first thing potential customers will notice when they check out your brand’s profile. The colors, layout, tone, and overall feeling of your Instagram page contribute to an aesthetic that can either gain you a new follower—or send them running."
First look at your target audience, develop core values, and choose a vibe. Consistency is very important, find out what kind of people you are trying to reach and stick with it.
Then, choose a color scheme! Cohesive accounts with similar colors really perform well. Just take a look at Lauren Conrad's coral tones and you'll see what I mean!
Finally, edit and plan. Stick to your aesthetic and your schedule. You can do it!
