Before you go any further, be clear about what you want to focus on. Trying to find all of their hoodies is nearly impossible, and collecting really isn't about trying to find all the hoodies the brand's ever existed with. Most collectors focus in, eras, collaborations, a certain graphic run, some kind of retrospective at the Palais Galliera. A well-defined scope will make sourcing, pricing and storage decisions a lot simpler than attempting to purchase everything.

The impact of condition grading is greater than you might think

Buyers who are not buying for a long time are not concerned with the "good" or "bad" condition of the item. That's not enough for collectors. Become  rick owens to assessing aspects of fabric such as pilling, print cracking or fading, condition of drawstring and aglets, and staining or discoloration in a specific and defined way and not solely based on a general impression. This is important when you're purchasing because it means that you know what you're getting, and if you ever want to sell or trade out a piece because it is made with precision.

Use separate spaces for Wear and Collection Pieces

Don't place a piece into regular wear rotation if it's really important to your collection. This seems like something obvious but it's easy to slip on something you like because it's comfortable and comfortable things wear out and worn things develop the kind of condition problems that take their toll on a serious collection over time. Before you start sorting, make a determination which are for wearing and which are for keeping and then honor that determination.

Documentation is definitely worth the effort

When possible, photograph the pieces as they are acquired, their tags, construction, anything special about them, and keep some sort of record of where and when acquired. This is unnecessary if you don't need it, but then again, if you do…for insurance, for future sale, or simply for you to keep track of which release that it belongs to. An undocumented and messy collection is truly difficult to oversee and difficult to establish authenticity for future.

Storage Needs to Match Collection Intent

It's not quite as simple as casual storage advices of hang it or fold it. If you have a piece that you really want to keep for a long time, it's more important than for a garment that you are wearing on a frequent basis that you use acid-free tissue paper to fold it, breathe-friendly garment bags instead of plastic, and keep it in a stable and dry environment away from direct light. Prints and color of the photos can fade and change over time, particularly when exposed directly to light, which is nearly impossible to prevent.

The Knowledge of the Community is Better than Guessing It Alone

For serious collectors, there is much to be gained from other individuals who have done the work of research. Fan communities, forums and expert resellers of releases, dating pieces and inconsistencies can provide in-depth information about specific releases or spot inconsistencies that would take you a long time to discover on your own. Please do not consider this to be cheating. Do it as a habit, as even the best collectors rely on common knowledge all the time.

Don't over-clean pieces you are preserving

Believe it or not, but over time, frequent washing (even gentle) affects the texture and the integrity of fabric prints. When it comes to special pieces (not the ones you wear on a regular day to day basis), less is more and you want to limit cleaning unless it is absolutely required. Keep the detailed care instructions for items used in the rotation.

Keep track of the market, but not necessarily your own portfolio

True collectors watch the general resale market, and not only their own collection. When you know what pieces are getting harder to come by and which specific releases are becoming more popular and how the price fluctuates over time, you can make better-informed choices about what to keep your eye out for next instead of just purchasing things out of the blue.

Be okay if some pieces are truly gone

There will be things that aren't going to be found, and trying to find something that's impossible can be a waste of time and effort. When it comes to serious collecting, it's about being discriminating and patient, not trying to find out every single thing that ever existed. Letting go of a certain piece is as much a skill as it is to know what to pursue.
