Look at this shirt (size XL) hanging on a standard plastic tubular hanger
Notice the steep 'drop-off' points in the middle of each shoulder.
This is sure to cause the dreaded 'Lumps'.
Now look at the same XL shirt on the MrBigXL® designer clothes hanger!
Notice how 'flat' the front of the shirt is. The hanger fits the shirt so well, the fabric falls naturally and does not gather.
