Do I have to have premium to trade?

Title. Ran into some generous fellow last night and he was going to give me a samurai suit but we couldn't trade.

@Perfect-Poizon yes but I don’t think it’s available in NGS you have to be in the old pso2, now I believe NGS items are Untradable no matter what but old PSO 2 items should be able to be traded and if one of you don’t have premium there’s always boxes that can go into your personal quarters with the items in it I did that with a friend earlier today(this way requires one of you to have premium tho)

Ah, I kinda get it..... but yeah ran into a cool fellow that had some extra Samurai outfits and he was going to give me one but I hadn't completed the prologue for OG pso2 yet. Bummer
