The 41-year-old British supermodel can't bear it when her pals rock up to her house for a party in casual wear, telling the Daily Telegraph newspaper: "I change my friends when they come to my house. Not everyone but if they haven't tried very hard and we're dressing up.
"I'll say, 'You're not coming in looking like that! In jeans and a T-shirt and trainers. Get that heel on.' "
But, although she likes to dress up to the nines, the blonde beauty isn't a big fan of red lipstick.
She explained: "[A gig] is not a red lip event. You're kissing too many people ... you don't want to leave stains on everyone."
Meanwhile, Moss likes to keep her make-up look relatively low-key most of the time, opting for neutral colours, but has admitted her simplistic style isn't something her 13-year-old daughter Lila-Grace has adopted.
"Lila's really into eyebrows and shaping them. She's got the same brows as me but she wants them painted in and shaped.
"I'm like, 'Right OK, they look like they've been cut out and stuck on your face but whatever.' I'm sure it all goes around and next season it'll be thin brows."
