Pence or Pounds?

First pic is of my absolute favourite dress of all time.
I bought it for 50p in the 'dressing up box' in my local charity shop. It originally came from 'West One' and each and every time I wear it I feel like a real broad. No necklaces, bangles or glitzy handbags are needed to add ooomph to this little number, a smile will suffice.

The second frock is yesterday's steal, being a surprisingly reasonable £9. Mind you paying £9 for something in a charity shop is insanely extravagant for me but I fell in love with it the minute I struggled into it in the shoe-box sized changing room.
It's made of silk with beaded detail at neck and hem and was designed by Edina Ronay who, I have to admit, I've never heard of, but it feels soft against my skin and shimmys in a most delightful way.

Now the question is...
Which one do I wear to next weeks Rayleigh Operatic and Dramatic Society's annual dinner/dance?

I already know...
