Oliver Goldsmith Y-Not: Y-Not, well why not?! One of OG’s most avant-garde designs, it is big, bold but most definitely beautiful. The jewel in the collection. Originally designed in 1966, the design is a celebration of the decade and is inexcusably loud and proud. Famously worn by Lady Gaga – who is a great supporter of the brand. The YNot features paddle (straight) temples which are embossed with its original production date. Handmade by craftsman using rich cotton acetate and premium grade UVA/UVB sun lenses.
