Where do you find Choice Specs in Pokemon Platinum?

Question

You can find Choice scarves and bands in the Battle Frontier, but no Specs? Where do you find them?

Answer 1

Go to Celestic Town's top left building (Celestic's "Pokemart"). Talk to the man in sunglasses in the Morning hours (04:00-09:59) for Choice Specs. The other times of day get you a Blackglasses (Day, 10:00-19:59) and a Wise Glasses (Night, 20:00-03:59). You can only get one of each.

Answer 2

In Platinum you'll get the Choice Specs from an NPC in the Celestic Town shop only in the morning (4:00AM to 9:59AM). This is the only way to get Choice Specs, and you can only get 1 copy of the item. Below is an image of the exact NPC you want to speak with.
