He's worn it a few times just wondering where it came from?

His own?

That's what I'm wondering, did he take his own long blonde wig in?

Bobby wore it during the task.

I think* the HMs were given props for the talent show.

Maybe it wasn't returned.

(* I could easily be wrong )

I could be wrong too but I seem to remember that wig making an appearance on top of Stevi's head before the talent show. I think he was wearing it on one of the occasions when the mankini was worn. I have a feeling Stevi brought it in for 'entertainment' purposes

You are probably right.

It suits him, it distracts from everything else about him

He's very fond of dressing up as a woman. Last night's task of a romantic date in the diary room said nothing about him dressing up as a woman for the evening.

Dressing up as a woman - the last refuge of the humourless man.

He also seems to have brought in a blonde woman he knows and is pretending he's in a relationship with her, for "entertainment purposes", both of which have failed massively

ha! ..

Spot on.
I'd like to add his eviction jacket to the whole 'entertainment package'.

If ever there was an award for someone wearing the most inappropriate (for him) jacket, the prize would go to Mr Entertainment Stevi.
