My Red Dot Glows For You
I realise this isn't what you want to hear but if you have to ask that question the answer is "no".
Agreed. Like all "unnecessary" purchases, it is all a matter of choice and prudence.
A $4,000 pair of sunglasses may be necessary if, say, it really gives you an edge over your Olympic trial rivals; or clinical reasons. The salesperson at the Bali shopping center may help you to convince you if the case is otherwise.
Personal choices may need some personal encouragement. Convincing is for a different level.
