Its (rather) long, its not brandable, its not street either.
To make this work you really needed the plural IMO.
I also don't think people will be searching for anything like this, its all going to be for product names, brand name + product name/model, or what the product is (smartwatches etc.)
Of course, it can always be SEO'd to do well for terms, but its not brandable, people wont remember you... you would get so frustrated that your decent tech ecommerce website isn't getting much traffic let alone sales, that you would burn serious cash on adwords and facebook adverts to retain customers. The margin would be so low its not worthwhile.
All entrepreneurs will be wary of this. Even if they called the website "Street Wearables" its going to be a big issue. I don't think its worthless, but reg fee. If you list it anywhere for above that accept Best Offer and just go for it.
