On the one hand, some people think that these two brands may be in different grades. For example, some people think that Sudi is a women's clothing brand that leads the street fashion. It is a first-line brand with a sense of fashion and a sense of texture. Poetry is an English Academy-style brand and a classic mainstream in the market, but it may not belong to the first-line brand.
On the other hand, some people think that they may be in the same grade.
Therefore, the classification of grades is related to specific evaluation criteria, brand positioning, market visibility, historical development and other factors. It is suggested that you can consult relevant fashion magazines or professionals in the fashion industry for more help.
