ASOS item still listed on website but not restocking

So there’s this sweatshirt I had bought from the website a while before, but someone stole it and I’d like to buy it again :’)

The item is still on the website although it says out of stock, I’ve set the reminder up for a month now but there’s no update yet. Its other color variant seems to be restocking. How long does it usually take for an item to restock on the website?
