I see a lot of variation in prices for clothing on the market. Some clothing pieces can be found priced at 700L, while others are around 100L, 200L, 300L. Occasionally you see some items for less than that. So I ask, how much should clothing be priced at? For say, a jacket, a dress, a top, a pair of shoes, etc. Should it be based on how much time and thought designers put into their work? There's also the factor of what people want to pay, but everyone loves freebies.
