Voila! The lace is beautiful on this dress, and of course we are all pleased it is fully lined. (Can you imagine? "Kate, we need a real distraction from Andrew right now. Can you go out in a sheer skirt and granny pants? No? No. Okay. Fair enough.)

Kate is gripping her clutch here but for a moment, I thought she'd caught William's old reliable Hands Clasped Genially Over His Crotch manuever, which in fact he is deploying here. (I'm not sure who this is that they're speaking to, but her shoes are so cute!)
