The original itself is sooooooooo pretty…I’d even stick with that. I think blue goes lovely with most complexions. You can try putting blue and peach clothes against yourself and get opinions from others to see what color looks the best with your complexion.
Otherwise…I think a peach AND blue combination is very pretty. Peach can also go nice against with mauve or dark pink. And peach could also look pretty against a smokey purple.
