The best way to offer a complete overview on all options available for your products: with one plugin only you can add unlimited variations (be they sizes, colours, patterns etc.) and show in an immediate and intriguing way all the possibilities for each single product in the shop are there.
YITH WooCommerce Color and Label Variations allows you to replace standard WooCommerce selects with icons, custom images and dynamic labels. The plugin is extremely versatile and adapts to any type of product: from clothes (for each item you will certainly need to show sizes and colours available) to jewels (maybe you want to show advanced options, such as gemstone form, necklace length o ring size, if the product is available in different precious metals and so on).
