'Her clothes were mentioned because it would seem she was half out of them and it was part of the evidence against her to show she was lying. Most people keep their clothes on if they are going for a late night walk in January'
To be fair she wasn't half out of her bra, she had a bra in her handbag so I think we can assume it was the whole bra and not one cup in the bag and the other one on her chest.
My friend's husband has regularly her spanx in his jacket pocket after a night out with her - she tends to whip them off in the ladies loo as the wine jollity flows. 
I better warn her not to get amorous in the car park go walking on the beach unless she wants her DH banged up for the night 
Feel really sorry for the couple concerned though, putting that much info in the public domain can be massively life changing for the worse.
