Some of my colleagues do get MTM suiting made in places like Hong Kong and Thailand.
The apparel market is massive I think there is room for innovation.

You say you spent 2.5 years setting up a supply chain, but did you examine the possibility of manufacturing in the USA?
Given that your polo shirts start at $115, surely there's enough fat margin to allow for increased costs? The federal minimum wage is just above $7/hr. How long does it take to make a polo shirt?
Why did you choose Thailand and not the USA? That's the question the Bloomberg interviewer should have asked.
In addition to my comments on your company name you should consider including a label of sorts somewhere on your shirt as a branding element (needs to be visible even if it hangs from the front or the tail). It doesn't have to be ala Polo or Tommy (over the chest) but there should be something to let people know that the product is yours.
Also I'm sure you have researched this but my gut says $100 is not the same as $98 in terms of consumer perception.
