Priya, Thanks for sharing the video. I think it's a very interesting question for Etsians. I liked looking at your shop, too. I don't think you have too many choices and it is definitely not confusing for me to look at them. I have a hunch that most people will come to your shop because they are looking for hair and shoe accessories in specific colors to match a formal dress, etc. So, the choice will already be narrowed for the buyer.
For Etsy sellers, the second concept in this TED talk is the most important: Concretize, make things vivid. For example, your photos are great and I can visualize how the flowers look in person and how they will match.
Ultimately, I think when a buyer comes to Etsy looking for gloves, hats, and other accessories, it is not like the choice to buy shampoo or a financial plan. It's an aesthetic choice and I think most people know more immediately what they like and don't like if it's simply a visual choice. At least, that's how it is for me. Give me thirty aqua scarves and it doesn't take me too long to figure out my favorite.
Furthermore, that fatigued, overloaded feeling is more a danger in Etsy's search results and not in an individual shop. Being very specific with tags and description will help the buyer in that regard by narrowing the search if they know what they are looking for.
