I've brightened up my colours and they are much more summery and fresh. I'd like to use the nudes (which looks a bit different on screen) and greys as a base with the other colours, mainly the peach and greens as splashes of colours throughout the collection.
Below are a few swatches I played with to experiment how I should balance the pallet.

I'm now going to dye fabrics to get a deeper sense of the colour so I can balance them on the body and play with proportion. The colours are still up for modification but this is the basic idea.
