Making the same clothes look different

Work outfit with sheath dress by eleanorbirdy featuring black leather boots

I've seen a few outfit suggestions recently that say things like 'One dress, four looks' then just show the same dress with small bits of jewellery and different shoes. 

If I'm going to wear and re-wear my outfits, I want to pretty much make people that think it's a different piece of clothing. A few tweaks of jewellery is just not going to cut it in the 'make people think you're not wearing the same things all the time' stakes.

So, I've got a lovely burgundy sheath dress that I'd like to make more use of (the dress above is the closest approximation I could find, although the picture looks more red than burgandy). 

I've worn my dress to the races at Ascot and a wedding (both in summer) but now I want to wear it for work in autumn/winter. 

I've got all the pieces above (or something like them). As you can see from the picture above, I'm pulling the formality of the dress down a bit as my workplace isn't super-dressy. I'd put the belt over the cardigan a) to keep warm and b) 'cos I like accenting my waist. For those apple-shaped folks, I'd suggest putting a wider belt under the cardigan - it still defines the waist but is more subtle about it. You could also make things a bit more fun with some subtly patterned black tights instead of just solid black.

 

 Above is another idea, again with items I already have some version of. Hopefully the change of colour palette looks different enough to not bring out the thought 'she always wears the same clothes'.Still, the style is definitely 'me' with the belted cardigan and tights the same colour as the shoes.

Now I'm running out of ideas. I don't fancy the idea of strong colour contrasts like navy and burgundy (remember my actual dress is burgundy) and heaven forbid I wear bright green and burgundy! 

I do have a pale pink cardigan which would look quite fetching with my dress. And I've got a nice pastel coloured statement necklace which would tie things together - with beige tights and beige booties. A bit frivolous, but could be kind of fun.

What do you think - do you mind wearing the same things all the time? How do you ring the changes?
