Whenever we watch Fashion TV our thoughts on items we see are either "Wow I could really wear this!" or we think they are complete nonsense. Many of us would agree that weird fashion trends are interesting to see on TV - but not to wear in public.
Firstly, by wearing something like that people wouldn't take us seriously. For example, we would never be able to find a job.
Secondly, people would make fun of us and they would think we are out of our mind for wearing that. Also, those type of clothes are usually very uncomfortable.
All in all, I believe that designers should more concentrate on designing clothes people would be able to wear in everyday life. In this way, it would be sold more.
