I need a pattern for Slim Fit 'O' Neck T shirt

I need a pattern/size chart for Slim Fit 'O' Neck T shirt
For manufacturers Use.

Slim Fit - Standard - Not Overly tight
Size S to XXL
O Neck


A size chart with all specks i.e. sleeve length/width.. neck width etc.

A drawing to show how to measure these (I have provided)
- please verify if suitable


Product is aimed at 18-25 yr olds.

I have an old T here at home. Prefer you have Skype or Yahoo so as I can show you on Cam to give you an idea of neck design. And also to have brief discussion about general fitting.

attached is sample of drawing and example of size measurement table

The drawing is provided.. all I need is the table measurements to be correct.

Thanks,
Charlie
