giant tartan/flannel clothing

I have looked everywhere for gigantic oversized (long) flannel shirts and/or drop crotch pants in “classic” plaid patterns (think red/green/yellow tartans or blackwatch or even red buffalo check). Prefer clean finishes without much distressing but I’m open to suggestions. Best examples I’ve found so far are CdG, but they’re often in very small sizes. Other brands I have considered and searched through: Vivienne Westwood Y’s for men/yohji Junya Old man’s tailor Lad musician Needles rebuild Issey Dsquared2 (ugh) Doublet Martine rose Miharayasuhiro Sacai Balenci A bunch more that I can’t think of off the top of my head No budget. Attached some relevant photos. The skirt I think has my favourite plaid but I wish it was pants.
