Most Effective Advertising Medium for Apparel eCommerce?

Hey all,

I run an apparel store through Shopify. We have found a lot of initial success through word-of-mouth and really want to keep our momentum going. We're going into influencer marketing (have found fairly inexpensive ways to get brand ambassadors), but I want to diversify our outreach and marketing.

For those of you who own or have owned an apparel store online, what has been the most effective advertising medium/strategy? We tried running FB ads and found little success, but it did provide us feedback on how to improve our website.

Any advice would be greatly appreciated, thank you. 🙂
