Help! Rock chick needs to look very conservative/dowdy/boring.

[Fabulassie]

I'm going to be doing a video for a friend's daughter's project. I am middle aged but I dress like a metal chick. I have only clothes that are dramatic and eye catching (I probably just look like an old tart). I need to look somewhere between mumsy and business.

I am going to wear my spectacles, moderate makeup, and my hair up in some dull way.

But what about clothes? What would a middle aged professional woman with a dull personality wear? I can't look striking or sexy. I'm very tall, thin and imposing so I want to play that down. I must not look cheap or slovenly, either. Just respectable and not even a little sexy.

I need two outfits, one for the dullest sort of office position and something that such a woman would wear outside of work, such as to go shopping or out to lunch.

This may all sound weird that I'm asking this, but I'm at a loss for how to dress utterly unlike myself.

It sounds like you are not after overly frumpy clothes, but just ones that are 'appropriate', not particularly sexy, attention grabbing or gives a hint at the external interests that person has. Not ill fitting completely, but not a huge effort to get something that flatters the figure the most. Tescos or sainsburys are your friends for this then. plus it won't be too expensive.

(I shall ignore the "conservative clothes = dull personality" comments, mainly because you chose to define yourself as a 'rock chick' clearly using your clothes to define your personality. not everyone does. Please don't call your style as 'chick' - it tends to set off a mental image of someone who's wearing stuff solely to fit in with an image, not just picking clothes they like, makes you sound like in real life you are a bit "try hard").

What zero says ^
This sounds like an Apprentice style video full of cliches.

Anyway I think the easiest thing is to just hit a charity shop and buy a few things which don't fit very well.
