I have found many special dresses on Ebay that I have worn over and over again. Most of them are from Tsumori Chicato and Marc Jacobs like the ones on the top picture. My favorite one is probably the one with the owl that Kinne got me for my birthday a few years ago. I usually save nearly 50 % when buying them on Ebay and buy them from brand.
I always buy my nailpolish from Essie on Ebay as well. The jewelly box is from London and the jewellery is inheritance from both my grandparents.
