Ciao chocolate-scented tshirt!

I was sniffing blissfully at my chocolate scented t-shirt.

Alas and alack,I had the sad knowledge that once I washed it with my good ole soap powder, the shirt's heavenly, chocolatey scent would be just a whiff of memory.

Which got me to thinking - while I understand that it may be more practical to sell perfume separately from clothing (and hence one can change the clothes' scent depending on the person's vagaries of mood and inclination), what if I were the type to want my particular ensemble to always smell like ginger? or mangoes? or blueberries?

Barring the fact that my chest of drawers will probably be eagerly swarmed by ecstatic ants if I were to stuff it with chocolate-scented tshirts, why aren't there more of such items?

Has a process been invented to permanently imbue clothing with a chosen scent - one which would fade slowly only through time (like how jeans color fades) and not through just one or two washings?

The usual flowery scents versus fruity scents is not a complete collection, easily available to the average person. What if I wanted durian-scented pants and a vanilla-scented top? What if I wanted lychee-scented shoes and watermelon-scented shorts? Its not as if I can just go out and buy from a perfume stand, a scent which I would like to spray on clothes or on my person. Have you ever heard of people manufacturing eau-de-durian or even a eau-de-raspberry?

*goes back to sniffing real dark chocolate this time since the tshirt now smells like Breeze laundry powder*
