Better pics might be good, for e.g.:
- consistent colour of background, middle-tone colour suited for bright or dark items as well
- no distractions, meaning no shiny parts, no ruffles in the background - your item is in focus
- larger space between the item and the background make the items pop
- always the same angles in the main page (from left above, front directly, whatever), that also shows consistency
- better light! Choose the room with the best light and shoot there, daylight is always the best
- most important: use models! Wearing a hat includes the hair, glases. How does that look like? Takea pic of a friend, or even of yourself. My first pics were alll me and my friends, now it is the daughter of my friend. My new collection I shot completely myself, with a selfmade backdrop. But you don't need a DSLR, (I did not have one for my shots here www.etsy.com/shop/EsozaFashion) even a goos smartphone would do. Perhaps shooting outdoors would be nice, your items remind me of holiday. Create that mood!
But hey, your sales are good so far, keep going!
