I just found a matte topcoat, which I had been looking for for a while.
I decided to have a bit of fun comparing the matt finish to a shiny one, so created this manicure with a dark shimmery purple.
I painted my nails completely purple
then applied matte top-coat
then painted the tips of my nails again with the purple
Overall I quite like the look!
