I am a bit limited as far as just buying off the rack. I need tall sizes when I buy long sleeve shirts and I need a 36 inseam. I also need to find shoes that are at least a size 15, maybe 16.
You can also scour amazon. This is a bit risky, since you’ll have to go to the hassle of shipping them back if they don’t fit. But it’s a quick way to sift through a lot of options for your physique.
