The decreasing fraction of traffic and sales largely depends on the fact that the visitors seem to be losing interest in your store which needs to be retained in order to maintain your site. The following steps should be followed to improve traffic and sales.
Hope your store gets better traffic and sales in the days to come.
Hi Filip! Maggie, Shopify Expert here :)
Sorry to hear about your low sales - yes, you should expect your sales to be increasing each year, or at least staying on a certain level. From looking at your website I cannot see anything that would put shoppers off - your images are high quality, it's easy to understand what you are offering and at what price from the very start, which is excellent.
If you have Google Analytics installed, I'd recommend getting a complete review of your traffic profile. It will give you information as to where your traffic was coming from months ago, why it dropped, and from which sources. The review will also look into where your most profitable buyers are coming from, meaning that you could then focus your marketing efforts to get more traffic from these sources, which is the easiest way to boost conversion rate.

I would hire someone to do a site audit and look at your past years and compare it to this year. How is traffic different, are people getting stuck on certain pages. Overall your site does look great.
Doing work around conversion rate optimization (CRO) and understanding where the roadblocks are will help you get sales back. A lot of this data will already be in Google Analytics, you just need someone to hunt it down and figure out what is stopping your site from converting. We do this for our ecom clients and it really does grow the business. Hope you found this helpful, if so please click "like" below to let me know.
