What colour is the shade? If white, then perhaps white side tables but change the handles/knobs to rose gold (if can find). It maybe a bit of a challenge but can you get a sample fabric and take it and the lamp to a furniture store?

I'm sure living in Sydney, you might come across what your looking for. Try going into ALOT of antique and secondhand shops, as they can be serious treasure troves right there. Also have a look at auctions as well, you can find really beautiful stuff there too! Also try websites like gumtree, eBay, etc.. you'll be surprised in the plethora of furniture being sold in those websites, especially princess style furniture! If you have exhausted all avenues and still can't find what you want, you might want to go to a cabinet maker/carpenter and ask to get one hand made. :-)

I think that top one from Amart will look lovely with the room and will definitely carry on with your timber throughout, it’s different, has a light wood that will pick up the white of the tables, I would love it myself. Are you able to get a larger photo of it and see how it looks near tables.

Black would look great, or timber with a touch of white
