A workflow that lets you use 8 reference images (seems to be the max), it is basically the standard demo workflow, with the added images, and with permanent random seed.

Prompt Guide

The prompt in the workflow lets you combine objects and concepts but the 6 image version is almost like an instant Lora training, let me give you the prompt:

Identify the same character that appears consistently across image 1 and image 2 and image 3 and image 4 and image 5 and image 6 and image 7 and image 8.
Treat image 1 and image 2 and image 3 and image 4 and image 5 and image 6 and image 7 and image 8 as different views of the same character, not separate subjects.

Infer the character’s overall form, proportions, surface details, and material qualities based on what is consistent across those views.

The character is named Bob. 
place Bob in a forest holding a cup of tea

The last 2 lines are interesting, you can nickname the characters in the different images and Flux.2 remember. The last line is where you use your normal prompting skills.

note that Image 1 will determine the aspect ratio

Transfer Cloths

Treat image 1 as the original base image.
Treat image 2 and image 3 and image 4 and image 5 and image 6 and image 7 and image 8 as different views of the same costume, not separate objects. 

Extract only the shared costume inferred from those references, preserving its geometry, seggmentation, surface detail, and material qualities as they appear consistently across the images.

Apply the costume form onto the character in image 1, aligning it to the target body’s proportions and contours.
Adjust scale, curvature, and orientation so the form conforms naturally to the body, wrapping, bending, or separating where appropriate.

Keep everything else from image 1 unchanged: identity, anatomy, pose, surface material, camera angle, lighting, shadows, and background.

Do not transfer anatomy, pose, or rendering style from image 2 or image 3 or image 4 or image 5 or image 6 or image 7 or image 8 Use those images only as visual references for the shared costume design.

The word costume pulls the weight since if you say clothing Flux thinks textile

In the 6 and 8 image version you can set the output resolution depending on your amount of vRAM. Just like classic SDXL high resolution might mess up the image, but i have had success wit 2 megapixel
