Both front corners are a mess…there’s overlapping faces and at least 1 extra face, folded in on itself.  There’s also a mismatch in the middle of the back of the collar (from the back centerline, it’s the 4th to the left…)

And fixing those seems to fix most of the problems…

Also, you’ve got the collar assigned to the same surface/material as the rest of the shirt, not the ‘white’ material. 

You haven’t UV mapped it yet?

Just because something costs a lot, doesn’t mean it’s the best…

It just means it’s expensive.

However;  if you look inside the left hand sleeve cuff, you will see what is called an interference pattern.  This is caused by more than one mesh inhabiting the same space.....

Also, if you select each of the selection tools from the lower section of this drop down menu sequentially, you may find a few more anomalies….

and, one more example….. I do hope I haven’t upset you too much, I’m not trying to diminish your TShirt but as the previous poster mentioned you do need to either work on it some more; or scrub it and start over again.  Either way enjoy yourself…  smile

Er, um,  you’ve got a hole in the left hand sleeve between the cuff and the bottom of the sleeve as you can see.  I’ve positioned it so that part of the collar (yellow) is showing through.  Sorreeeee.  You’ll be hate-ting me so I shall beat a hasty retreat…..

This curve is an exact copy of the shaping of the collar when viewed from above .....

Lastly, with the shirt body removed, thus showing the contours of the collar…..

Perhaps the real problem is that all of the normals of the collar have flipped, starting at the seam where the collar connects to the shirt.

Confirmed at this end as well, but I had commented enough.  One reason why you couldn’t make/keep your shading domains. 

For if you attempt to flip the normals etc after you have designated your shading domains, you will loose them,  that’s why it is important to check/adjust your normals prior to designating any SD and/or mat’s.  Why one should only designate SD/Mat’s after you have finished modelling, but prior to UV’ing.

Well, I’ve tried various ways to add tessellations to the shirt & on every attempt it crashes Hexagon.  If you/or anybody else has similar problems then to be brutally honest, I think you should start again you will find you will create the mesh twice as quickly as this one.  There is in my humble opinion something seriously wrong with this mesh and its not, too many poly’s.

EDIT:    Doh!!!!!  I’m a twit, I’m a prat, I’m a wrinkly idiot; you’ve collapsed the DG.  I’m attempting to add tessellations to a smoothed mesh = wrong!  red face  red face  One silly nearly 73 year old man will now shut up and slink away with tail between legs. I should be put down mutter, mutter, dribble. Perhaps I’ll pop my clogs before they come to take me away.  LOL

Seriously;  make a new mesh.
