Hi Binita,
You could try changing your tags on some of your listings (but don't do all of them at once). Test-drive some new, different tag phrases and see if they get you more views.
However, your items are coming up on the first few pages of several relevant searches, so I suspect that the issue is more about your photos than your tags and titles. Your photos aren't bad, but they don't really jump out at me either. I'd like to see brighter photos with a bit of style. For instance, you could drape a doily over a nice wood table, or photograph a handkerchief artfully tucked into the breast pocket of a blazer. Obviously you want to keep it clean and simple - too much stuff in a photo can look messy and confusing - but a bit of flair can go a long way toward getting people to click on your listings.
