Are some of your friends online marketing experts? Do they study the trends and understand the dynamics of content creation?

I am guessing your friends read a ton of fashion blogs, they just don't know it.

The short version of the advice would be: use your WordPress blog as the hub of your entire online presence. Then use the social platform of the week to build and connect with your audience, and give them reasons to come back to your site. Whether this is SnapChat (stories, filters, etc), Instagram (featuring highlights of a fashion shoot, etc with more details on your .... you guessed it: blog), or Facebook teasers with links back to your site.

Nearly every major content producer understands the importance so maintaining your own platform (your blog, in this case). Social media trends change, the ability to access your audience changes (Facebook is always changing their algorithm, and rarely in favor of brand pages), there will always be a new Snapchat, Pinterest, Instagram, etc .... but when you control the main hub, your website, you can stay connected to your audience much more efficiently over time.

Your assumption is correct: use social as the "spokes" that lead visitors back to your hub.
