AAA Tall Tees?

Hey everyone..
I recently got some tall tees from AS Colour, but they are fairly lightweight (180 GSM around 5.3oz) I am looking for something a bit heavier and thicker.. 
So I was scaling the forums and found out about AAA style tees.. went to their website found a distributor in Australia, but then I seen a picture of the tall tee and it looks baggy all over, very wide.
Does anyone have any experience with what sizing to buy when purchasing AAA tall tees.


Also on a side note I have found a decent manufacture in the USA for 5 panels/snapbacks/pom beanies/beanies, and am getting some made up soon! So stoked, have been searching on dead ends for months to find someone decent. 

I'd check out Alstyle 1301.  We were pretty pleased with the samples we received and great in terms of the variety of colors to choose from.
