It;s a tie between pinks and purples. I loved and wore a lot of pink and purple as a child, and then rebelled against the "girliness" of it as a teenager and wore only earthy tones, which were really not that flattering. As an adult I've decided I can be a feminist who loves pink and purple. It's beautiful and also what looks good against my skin, so I don't fight it.

One thing you can do to help in this situation is teach her that it's safe to talk to you about things that don't seem to be 'right". Make it a habit to wonder out loud together if things are being presented truthfully. Look things up on the internet together. Keep it age appropriate, but be someone who explains things to her well. I taught my children early to question if the things they heard at school were true and they'd ask me. Your parents will probably always be in the position to do that, but you can make an effort to be there, too. Then when she's older if she starts to question things your parents told her, she'll know you're a safe person to talk to.
