I'm attending my first conference next month, a two day conference in London for a charity raising funds for a disease my son has. I know several other parents of children with the disease who will be attending through social media though I've never met them, so want to make a good impression. I have no idea what to wear/what's appropriate, please help.
I'm a 30yo SAHM, I live in jeans & converse. I'm a size 18-20 and can't walk in heels! Thanks.
