Hi Erin!
I would expand your titles. I know it looks messy, but the more search words in titles, the more chance of getting found.
For example, you have 4th July in your tags for this t-shirt, but it's not in the title. When you type in the title bar, it will show how many characters you have left. Use as many as you can with searchable words for the item!
Also, add measurements for sizes. Length and width in both inches and cm.
