If you're someone like me who likes to collect the outfits for your class, you will reach a point where your 192 alloted slots for Pearl Shop items will become full. Another factor is this new thing where outfits that used to take up 1 slot for both pieces (gloves + chest), and (gloves + chest + head + shoes), are being separated to have their individual slots taking up more space in your Pearl Inventory.
Other than outfits there's also Advice of Valks and other non-outfit items that take up space.
At the rate Black Desert is releasing outfits for our classes, you'll get there sooner rather than later
Personally, I do not buy all the released outfits. It needs to give me a spark of style when I first see it. Some of the things I consider when buying an outfit, similar as in real life are, style, function, and relevance. I'm not naming the outfit but they released one that looks like plastic bags sewn together, and not in a recycle-to-save-the-earth kind.
One of the things that helped me manage my Pearl Inventory is Patrigio's Apparel Bag. I think we got 1 for free, and another in Loyalties but we can also make 1 weekly by taking the weekly quest [Weekly] Morco & Patrigio's Apparel Bag from Morco in Velia. This is a weekly quest so you can only get this once per week.
NOTE: Skilled Knowledge Certificate required for processing the materials. Do not confuse with Skilled Level processing. Without the Skilled Knowledge Certificate, attempting to process the final materials needed will fail.
Once you have Skilled Knowledge Certificate for processing, it's time to collect the materials. The materials can be quite tricky if you havent invested in the nodes early on, you can still buy them off of the Central Market, but will take some time. If you're only investing in the nodes now, I suggest to put an Artisan Goblin, but at the same time PO the required materials from Central Market to speed up your material gathering.
