The top feel like it is 60% of the thickness of my Landau tops.  The top isn't bad.. The pants are terrible and why I won't buy these again.  They are probably 1/2 as thin as Landau, I assumed that regular pant pockets were standard and these only had the 1 side and 1 back as extras.. but these pants literally have.. 1 side pocket and 1 back pocket... useless for a nurse.
The pants waist band is large..  I am 5'11" 140ibs and small fit.. but I have that drawstring all the way.  The drawstring is cheap too.. I couldn't get the knot undone to remove them just now after testing.. they are worse than my hospitals OR scrubs.
All in all the shirt gets 3.5/5 stars and the pants 1/5..  Im averaging it down to 2 since you have to buy them together.
