The short answer is yes. And congratulate. You are getting into the right market, in your case: sell teen clothes. Why do I say that?
Take the USA apparel market for example:
The apparel market in the USA has a very positive signal according to Statista data. The market size is projected to grow from US$225billion to US$285 billion (2012-2025) at a rate of 2% (CAGR).
The same institution’s research indicates the user penetration rate in the global apparel segment to be 33.3% in 2019 and by 2023 it’s expected to reach 44.0%. The junior age is the majority in this case.
But where to find good clothing suppliers for teenagers? That is another story.
