You want to sell online? There are many different ways to show your merchandise. Some are specialized, while others can work for any boutique.
Facebook-This has multiple ways including posting merchandise in folders or live sales.
Instagram-This is more of a single item or outfit as too many photos will make for a messy feed.
Etsy– This is especially good if you make the clothing yourself. One downside is they have higher fees, but that comes with a large customer base.
