I don’t think looseness is always more comfortable. You need looseness in the right areas which is what tailoring provides.
Maybe it’s cold and the extra airiness is working against you.
Maybe the clothes rustle and rub more when you move.
How do (non-elastic) pants stay up, without some minimal measurement for the waist?
I own some more baggy T-shirts and layering with a sweater feels more uncomfortable because the clothes will fold in places you don’t want them to with a sweater on, which is not a problem for more trim fit clothes.
