I was shopping in Fashion Galore when I bought an article of clothing for my HA. After purchasing the clothing, I was sifting through my inventory and I found that I had two of the item I bought. I knew that I hadn't bought more than one by accident because I had gotten the last one in stock. Then I realized that I had already bought the item before, but I had forgotten about it. And by my next shopping spree, I had bought another without knowing that another one was just rotting in my inventory.
That's happened to me a lot. xD
So I was thinking, maybe when you're shopping and you see something you want to buy, there could be this little phrase below the item stock. The sentence would say, "There are ___ of this item in your inventory. There are ___ of this item in your gallery. There are ___ of this item in your collections." And in the blanks, it would say the number of stock you had of that specific item. That way n00bs like me wouldn't make the mistake of buying things they already had. :3
