Illustration for logo plus small thank you card design

I’m wanting a logo for my online retail business. I sell mostly secondhand items - predominantly clothes, all online. Part of the message behind the brand is to encourage more sustainable practice, shopping secondhand items. The logo will be used as part of the shop front on ebay, on my social media, and on some thank you/feedback cards i will include with purchases. The name of the shop is Recycling Rainbows, so i'm wanting reference to the recycling nature of the business, and for it to be colourful/rainbow related. I have attached a picture in the sort of style im after, and am open to ideas about what to include in the illustration. i was thinking rainbows similar to the image with mannequins in different style/colour/pattern dresses/clothes as the focus? something along these lines anyway.
