Well i guess a big difference with the streetwear/sneaker reselling is that its on contemporary releases.
A lot of these scarves i have are 20-40 years old. Their release window is well up and whats out there is out there. Prices can still get pretty astronomical based on how limited/rare it is, and if its a popular scarf artist, and ehat condition it is. Which doesnt really make it took different than normal antique sales.
