Triangl has a bad reputation here in Australia, it's an Australian company and my wife's sister actually knows Erin Deering (who founded Triangl), not on a phone-call basis, but has met her at different industry events and knows people who know her.
The general opinion is the quality is cheap because they went overseas and chose the first supplier they found, but didn't really check the quality of what was being produced.
So what regularly happens is a lot of the items that Triangl sells have manufacturing defects and I am talking things like: straps breaking off, printing issues, stitching coming undone, material tearing and the biggest issue of all is: cup sizes being incorrect.
Looking at the reviews on Site Jabber, it seems many are complaining about sizes being incorrect, I can tell you that this is a really common occurence. This company is horrible.
