I am not a fan of neon colours. I like softer colours and bold colours as accessories. I have seen people in all ages wearing different shades of pinks and some look awesome and some look awful. I think how one carries themselves and the rest of the outfits really matters!I agree with diane278
With the exception of neon colors— if someone can show me neon pink or green looking sophisticated I will be very surprised. Also bright colors have to be used in moderation, I think one piece maximum in an outfit.
I mentioned pink because (it might not be evident from the pictures I chose) but the IG girl often wears a LOT of pink. It looks super cute when she does it but I think past a certain age, wearing that much pink goes from “cute” to “yikes” . Just my opinion
