Hi, I took a look at the campaign and have some comments for you.
I can see you've raised about 15% and still have some time to go, so that's ok.
My initial impression is that it's too sexy. It's designed for women, but the campaign looks like it's aimed at men
I think there's a difference in the quality of the photos. The photos of the model look very high quality, but the photos of the thongs laid out on the white background look a bit dull and it think it's difficult to tell what they look like without them being worn.
I also would of liked to of seen other women wearing the thong, perhaps as a group - that way the viewer can gage different body sizes.
Can the thong be used on the beach, in the water, on a boat? Having photos of the model wearing it in these locations would help too.
What I'd do is is take photos of the thong worn by a shop dummy. That way customers can't get distracted by a hot looking woman and focus on qualities such as the material, colours and ultimately if they can wear it.
I don't remember seeing a size chart, I think it's important.
Also bullet points of what makes your thongs better than those from the regular high street I think are needed. The video and sexy model have probably helped to get you backers, but in tern it may of diswayed potential customers who were more focused on how it would fit them.
Another thing is who you've reached out to? What did they say?
If you need further help with your campaign let me know and I can give you some further ideas on how to progress your campaign. All the best!
