Everyone has their goals in life and some are just able to do just that. For the rest of us it's either due to lack of funds or lifestyle rendering the envisaged result as being outside our reach.
Spook has to be admired for what she is attempting and good luck to her. Personally her ultra small frame and waist do nothing for me, but I will not condemn her for her choice.
As for cling film covering a person I can see some practicalities, such as increasing sweat production in certain areas to help with weight loss and associated problems, but as a fetish item it doesn't appeal. I do find many things erotic and sensual, but each to their own. If someone disagrees with my points of view then I can only say that it's my opinion and I'm entitled to it, just as everyone else is entitled to theirs.
On a plus side, I would love to own or even just try a pair of ballet boots on just for the experience. I shall probably end up flat on my back or face, but what a laugh

To me they are the most erotic style of shoe you can get. I have seen various others styles like pony boots which don't seem to interest me, but that's where likes and dislikes come in. If I saw someone wearing them I would be curious as to their capability to walk in them but would not ridicule them for it.
If anyone in UK has a pair of size 9 ballet boots available, let me know!
