that's always the best idea. usually we intuitively know what feels right.
it's funny, I actually think that Hermès is doing a poor job in that regard with their modeling shots for their scarves. The model they use for most pics is clearly of a soft coloring and those soft colors look beautiful on her. but then they stick her in these bright scarves and it just doesn't do anything for her... here she is in warm and some bright colors. i feel like it makes her skin look a bit dull and orangey

while when you look at her in more cooler toned and softer scarves her skin looks like it's glowing and there is color harmony.

or maybe I'm imagining things lol. It probably is all for the better though because if they would be as good at scarf modeling as tpf ladies are, we'd all be enabled into bancruptcy
