I love that you were such lovely dresses op, and make the effort. Im a jeans, leggings and hoodie girl and wish I could feel comfortable wearing the lovely styles you like!
However, my two pennies worth, the white one is horrible - I don't think it would do much for anyone, IMO its fit for the chairty shop.
The blue one and black one are just so lovely op, totally agree with PP, they are your colouring, your style, very flattering. Really like how you matched the blue dress with the blue trainer shoes.
The second photo of the orignal dress, im so sorry op, I dislike it even more than the first. I think the necklaces help with making it more accessorised, but it just really isn't the dress for you.
I hope my response isn't taken any other way except for nicely, I think its lovely you try different styles and make effort.
