Most clients of my agency is the branch of fashion, so I must constantly provide templates that allow clothing catalog and / or portfolio of fashion products with vertical photos (portrait style). Any template that allows pages to do so?
You can change the default product thumbnail dimensions on the WooCommerce option page (WooCommerce > Settings > Catalog). You can change the dimensions and i.e. set a higher height value and a lower width value. This should give you portrait images. Afterwards regenerate the thumbnails with: wordpress.org/plugins/regenerate-thumbnails/
That said we have no special “portrait image” or fashion themes in our portfolio.
