Photoshiop Manipulation- Printing onto a dress

Unfortunately I don't have time to test this print onto a real dress, but I can simulate the outcome using Photoshop:

I used the image of a vintage 1950's dress from Inspyre Tash Stock as a backdrop garment for the print. Before I could paste the image onto the dress I had to delete the background it had around it.
Then I tested what the dress would look like both in colour and in black and white.

I prefer the colour version because I think the red lips and blonde hair contrast well against the blue fabric. However, I'm not sure how well the colours would come out on a coloured fabric.
