I prefer quality over quantity, weather it's new or second hand doesn't matter as long as it meets my requirements of being well made.
For instance I would never buy a new car, a mid range car that costs 10k just doesn't add up I would much prefer to own a 7 year old car that was 50k new for the same price.
Clothing I limit to a small selection of well made products, items that fit well and are made to last/ preform their job well for many years. For instance a quality winter jacket bought in the summer sale for half price lasted 10 years before it started leaking and I never waterproofed it once in all those years.
I have a little motto that is almost always true.
Buy cheap, buy twice.
