is blip necessary for training?

I see that for inference, if blip is applied, the result will be better for some categories of cloth other than those in viton-hd, like jackets or bikinis. So is the blip part in the figure of this repo necessary for training?

We focus on the generative capability of our model, so the prompt is necessary. The virtual try-on function is just a fancy extension.
