My suggestion?Well, I had a pair of Flaks (Polished BLK/BLK Irid) that were lost/stolen on a cruise. I loved the glasses, so I bought another identical pair. Then I came across a pair or Canteens (Polished BLK/Chrome Irid/Pol) and decided I needed those too. Had a hard time deciding between the Fives Squared and the Canteen, but the Canteen won me over as I was looking for something with a bigger lens that fit my weird elongated looking head. Then I bought Mrs. Conductor a pair of Polarized Tortoise Pulses, then I started looking for more, so I signed up here
I don't envision myself getting into collecting, but I do like to have an assortment and stay in the know.
Buy at least 3 of every frame you like. This way if they become discontinued and something happens to one you have a couple of more backups.
