I’m sharing an observation from a fashion/product-imagery perspective that may be relevant for image generation realism.
Current image generation models tend to render double button rows as purely decorative elements. However, in real garments, a functional button placket is defined by two overlapping fabric layers rather than the buttons themselves.
From a visual perspective, the difference is primarily conveyed through:
-
a clearly visible fabric edge of the upper layer
-
depth-dependent shadow gradients between the overlapping layers
-
locally reduced shadow intensity at button positions where layers are pulled together
This could potentially be implemented without retraining the model, using a post-generation step:
-
detect a vertical fabric edge adjacent to one button row
-
apply variable shadow intensity along the edge
-
modulate shadow strength between buttons vs at button positions
Trigger condition could be prompt terms such as “functional button placket”, “button closure”, or “overlapping fabric closure”.
This would greatly improve realism in fashion, workwear, and uniform imagery while requiring relatively low computational overhead.
I’d be curious whether others working with fashion or product imagery have encountered similar limitations, or if there are existing approaches I may have missed.
