-quality construction of garment
-quality of fabric used in construction
these are two very different things and can create confusion
this is why i say that OP brand can yield good results for some things that designed to be tough, like jeans, jeans by their nature are designed as tough garments, idc if you buy wrangler, or whatever, me personally, NEVER have ever owned a pair of jeans that actually fell apart on me, I've ownd shit brands that have been washed thousands of tiems and still been fine, because they are jeans JEANS.
it's not expensive to construct jeans that are durable, this is just fact. but it is more expensive to source highest quality denim and re wash the jeans hundredds of times like the Acne stay black jeans, that process COSTS alot of money to do, tbs, this doesnt mean the actual threading and construction of that 300 pair will be any better than a 20$ pair at H&M. this is just the reality
yes you can see a shitty cheap quality cotton shirt on someone, if you have that awareness and fashion ability, but most people cant.
the more you explore Fashion the more you will realize there is a difference in good fabric vs cheaper fabric, but someone could construct a really bad stitched shirt that has quality amazing fabric in it also.
so in terms of durability, I dont think that that should be the argument point, because you can just go and buy Dickies and pay nothing and have very durable
high quality SOFT fabrics like silk and even just rayon, these are no durable fabrics but they will cost more than cheap spun cotton.
my point is, you shouldn't pay premium for "durable" clothes, because durability is not expensive to produce. just mass produce a shirt that is stitched well, and use ultra cheap cotton, the cotton wont rip, only the seams will rip.
