Long-sleeved polo made of viscose premium jersey

The two long sleeve jersey polo's I purchased were size XS. I was informed by your customer care that Phil Petter has discontinued size XS across all lines. I was also told that sizes are now being designed with larger profiles across all sizes. Some of your size small that I have ordered appear to be made on the old smaller profile, but many are too big for me in size small. I am 5'9" and 150lb. With discontinuing the size XS are you now reverting to a smaller size small?
