I have an idea that might improve that in several ways.
At the moment it looks cluttered is almost to much choice. Instead of giving a separate icon for each colour of clothing, why not have an icon for each unique type of clothing, then a slider, or a selection of available colours. This appears to be partly implemented with the main and trim colours.
Would make it less cluttered, and if a slider, would make more choice for user. Even just a selection would be much improved UI and make the screen less daunting. Any reason this shouldn't be in, other than of course time to recode it ?
