Why does one need seven pairs of sunglasses? I guess you are SoCal so it's okay haha.. I would probably want two-three pairs (metal, plastic tortoise, and plastic solid) and be done with it.
VB) White leather wrapped aviators
DD) Thickish metal kinda wayfayer style
RS) Painted plastic large lens thing
RS) Black sheild lens
RS) Ovals with leather guards
RS) Orange metal aviators
DvN) 50s retro thick plastic
Also I have a pair of tortoise kinda Wayfayer style from Cutler & Gross.
