Womens clothing tends to be worse as even more expensive clothes are sold by dress size or the generic small/medium large and only a limited number of items offer any build variations for an item. Next typically offer a petite and a tall range for some items, but not for all and they quite rare in high street retailers offering that.
Men you tend to find a waist, length, chest, neck measurement in cm/inches, which is far more useful. A lot, but not all, of trousers with actual measurement on them also offer different lengths, and in some cases different cuts (jeans are very good for this).
Nexts shirts, like a lot of high street fashion, have two broad ranges for men, casual and formal. The former is shit for sizing as its the small/medium rubbish that I wouldn't touch with a barge pole, not least because the arms are always too fucking narrow for my arms. The latter most definitely comes in a range of body fits and actual measurements.
The best clothing is sold by the actual measurements of the garment so you can actually compare against stuff that actually fits you. I typically get stuff tailored from there as I buy larger to fit my chest/shoulders and its too long. Its not expensive (about £15 for a t shirt) if you are not buying endless fast fashion garbage and buy stuff to last instead.
Does he put forward his case that he is the anti christ? As he sure comes across as someone who would want that. He has always felt like the sort of motherfucker who would read the Stand and identify with Randall Flagg
