Well, of course!
I happen to play a bard (female elf, chaotic evil) who does exactly that: she is a producer (and consumer) of the finest crafts you could find: perfume, fine cloth, you name it. She can craft all sorts of goods, but is especially good in making women's dresses. After gaining access to level 6 spell slots, she has begun to produce a special kind of dress:
A fine crafted dress enchanted with a level 6 spell "major image". Since it is level 6, the illusion is PERMANENT, and there is no restriction on what the illusion exactly does. So you can cast it on a piece of cloth and make it look like it's on fire, or a swarm of shining butterflies surrounding it. We use this mostly for "skins" (as my friends call them), but you could, however, cast a camouflage pattern or even something more exotic like a illusion that makes you slightly invisible by breaking light around you.
This is by no means flawless, as you can always "dispell magic" the dress, but you'd need a high spellslot for it, and you would not gain anything from it other then destroying a valuable piece of clothing (like in: you cut your best dress open, it's your fault).
These dresses gain a huge amount of value since royal people are always interested in extravagant style, thus my bard gains access to the rich and wealthy, and since she's mainly an enchanter, she can mind-controll a rich person easily and rip of all their values. Of course it helps if you can produce more goods, like all sorts of magical perfume, or have access to magical fibre that generates more and more value on a single dress.
I hope this could help you.
[EDIT: I just realised after again reading your initial comment, that you seem to mean "change the appearance at will" , well, those surely exist too, like a "hat of disguise", but it's more common and practical to have somebody burn a low-level spell slot to disguise the whole party rather than producing something like said hat]
