blu collection, good/bad?

I just found out my gown is part of the Mori Lee 'blu collection', is this a good or a bad thing?

What does this mean?

I spoke to the manager from the store and he said the reason I can't find it online is cause its part of this collection...

He said 'don't worry its a very good thing'... but i'm a lil concerned...
I want to post my gown too ....
