For me, whether the item is expensive or non expensive, the most important thing is the fit. A non expensive item fitted really well can look much better than an ill-fitting expensive item. Obviously there will be a difference in quality in terms of materials etc..but that is something we all have to deal with!!!
It comes down to affordability I guess.
I was out one evening and some fella made the effort to come over to me and said he really liked my blazer, where's it from.......On telling him I got it from H&M he turned his nose up, when 10 seconds ago he liked it!!
Like I said "the most important thing is the fit"
