don't know why every reincarnation Otome novel revered the silk fabric so much when there's not much design you can do with it like those beautiful gowns with different kind of fabrics that was much better. silk can be used but for a few parts of the dress and for design decoration only. Asian dresses such as Chinese dress and other Asian culture dresses such as Indian dress can be used but silk mostly used for sleepwear only.
Also it just my opinion but most silk dress use in western-style looks too cheap for me.
If I were Iris, I would have used my future modern fashion style, that can abide by the nobles dress code but slowly changing the fashion trend, since in this timeline they only use frills and a ballon dress so having flowy but beautiful dress would be more trendy and beautiful and that would profit me more.
I thought she's smart, I guess she's not that smart.
if she's gonna advertise a dress then advertise a dress that can use different fabrics that are easy to obtain and use and make it into something beautiful that no one has ever done like off-shoulder with simple yet unique but elegant design.
Advertising a dress with silk that is hard to obtain and only limited is just stupid. if your gonna introduce silk then introduce by showing it as to what it really uses for such as silk that was made for its traditional dress style. it's from oversea right, then it should be made with the countries' design dress code, that would have piqued the people's interest and appreciate the beauty of the silk if its use for its true purpose and showed the real beauty of it.
