This whole topic has kind of split into a couple of different ideas. I'm going to try my hardest to rain on everyone's parade at the same time.
Purses (as reskinned wallets/briefcases): Just use a wallet or a briefcase. There are at least two of each of those to address a variety of needs. Every time you add an object to the game it's adding to the bloat of the game which is something the admins seem to always be combating.
Your generic purse item will not make you more unique, and its functionality is already addressed by the item you're attempting to copy. It's just unnecessary in terms of functionality and if you want a nice look you should be looking at tailoring things instead.
Purses (as tailored objects): Tailored objects are just clothing items. You can wear them. You can apply certain messages to them. You can make them pretty. What you can't do with tailoring is add functionality to an object. You can't make disguises for a reason. You can't make containers for a reason. This rules out being able to make nonfunctional purses and backpacks and the like as well.
And simply having a purse object created and choosing to RP putting things in and taking them out kind of betrays the idea of the game giving you consequences. If you walk up to someone and steal their wallet, you get their wallet and all the contents it may have. If you walk up to someone and steal their tailored purse, you only get a purse.

Why not let a person be able to tailor a purse object -and- add wallet functionality to it?
First off, as things stand, that would allow you to make wearable containers, which prevents many forms of theft. Worn containers are few and far between and are only designed, at the time, for weapons. This would create a weird new issue to balance out, since one principal of the game seems to be that you should be able to have most things that you aren't wearing snatched away at a moment's notice.
And simply adding functionality to tailored objects creates a weird situation to handle too. If you make it so a tailored item can function like a wallet, you're making a situation where people can turn their pants into a wallet so they can stuff their chy into their pockets and then, again, be immune to easier theft with worn wallets. It allows situations which barely even make sense too, like walking around with 10,000c stuffed into your panties, along with the nude photographs of your lover. Now you've got a worn container that can be hidden underneath other objects.
And while none of these ideas are strictly bad, it would all require extensive thought about how they would effect the game, and if you would want those effects to be a possibility. If you want the effects, but then want to be able to counter those effects with something else, that requires even more coding work which then, too, probably requires some thoughts and time spent on balancing it.
And all this time spent just on making it so you can have a purse.
