I think it's sadly inevitable people will comment on her body, firstly as a woman in the public eye, or girl, your body will be commented on, the Beckhams know this and still choose to expose her. Secondly because Victoria is so thin and has obviously eating disorder Harper's perfectly normal body already looks big standing next to her mum. Again, they know this.
Is it ok? Not really, but her parents are putting her in plunge necklines at 11, the clothes don't scream little girl. I think it's all gross, I feel sorry for Harper as she's not naturally skinny and will be forever compared to her unnaturally skinny mum, she's a lovely looking normal looking 11 yr old and if her parents had an ounce of decency we'd have no idea what she looks like.
