meta description on product categories?

Im using woocommerce for the first time on one of my sites, and i have stumbled upon somthing that i see as a problem (hopeflly and most likely there is a solution to this)

My shop is built up from product categories. And in this example the site is a fashion shop therefor my categories is as follow:

Bags
Jeans
Jackets
Shoes
Shirts

And below these categories i have all my product.

NOW!
In Google if someone seach on “bags” and my category about would show up ie. www.myfashionshop.com/bags My meta description would be from one bag that i have in this category.

But i want in some way to write my own one so that it would suit the product category in a good way. Is there any way to fix this or do i have to make “pages” with my category name and then have 1 shop on each page?
