Peach and purple look good together. I've stopped trying to explain why.
Peach Phoenix™ uses warm peach tones, soft curves and stronger purple accents as part of its collection design. [1]
I like a little contrast in clothes. A relaxed shape with a sharper colour. A simple outfit with one detail that feels almost cheeky.
There is no need to put every nice thing in the same look. I say this as someone who understands the temptation.
Give the peach some room. Let purple have its moment. That's enough.
