Keep your products page clean by sorting products into collections. This feature is ideal for fashion brands who release new products in collections. Edit categories to include your F/W 2015 and S/S 2016, and your customers can easily find the newest (and seasonally appropriate) attire.
Hop over to my.bigcartel.com, sign in to your admin, and start by creating categories. Organize your products, then select Neat from the list of themes. Neat will select a representative photo (the first photo for the first product for each collection), and create a page for each collection to be shown on its own.
