I honestly think we need to stop torturing ourselves by using cost per wear as a justification. Scratch that from our vocabulary as it is doomed for failure and certain to bring guilt.
Many people take big, grand vacations every year which is a costly expense. Vacations are one-time events, so definitely not cost friendly. Oh... "but you have the memories" one might justify. Yes, you do, the memories are forever in your head.
Well, with bling, we can one-up that!
No memories needed... the bling is right here, forever in the present for us to keep staring at, every day, all day!
Just go for the bling you want and enjoy it. No guilt ladies. Men never have guilt over their expensive toys; we should not either.
