Don't give up, it does take some time to build a following and start getting steady views. The first thing I noticed was your titles. The first three words in your titles are the most important for you to show up on etsy searches. For example, I would probably start my titles as "slouchy hat grey ..etc". It may sound weird but it will come up on searches more.
Instead of thinking about your descriptions being braggy, try to think of it as being as descriptive as possible. Google uses your descriptions for search engines, so the more description you have the more likely you'll pop up there.
The more items you have the more likely you'll get found. Social media is great, I get the most views from twitter, facebook and wanelo. I post every new item onto all of them. Join more teams on etsy and get involved in the forums, most sellers on etsy are also buyers. They favorite your item, your item shows up on all their followers activity feed.
Your pictures could look better too. You want to make your hats really grabs someones attention while they are looking through thousands of hats. What I would do is look at other sellers who sell similar type products that are doing really well on etsy, and see what kind of pictures they are taking for ideas of how to do your own.
This team is really helpful. I have learned a lot in the past 6 months and buy implying things I've gotten from this team have turn my one sale a month to 8-10 a month (Constantly working to get better each month)
