One is a limited-edition pair of Liberty-print sunglasses by RetroSuperFuture. Handmade in Italy, it features Liberty's classic Nina rose print, has Zeiss lenses and is available exclusively at Liberty for £120.
The other has a remarkably similar rose print, but is available nationwide in Primark for just £1.
I know which pair I'll be buying. Plus, it won't be a worry if I accidentally sit on them or lose them! Get them now ready for festival season.
Btw, if you hadn't guessed, the Primarni version is the one on the bottom.
