Enhanced Costumes Guide

You now have the ability to more fully customize your FarmVille character with all new types of clothing, including shirts, bottoms, shoes, accessories and a variety of costumes, just in time for Halloween!
.

A few basic clothing types will already be in your inventory, and the rest you can browse through before purchasing. You can even see how they look on you before cracking open that wallet (or purse). All you need is to be level 4!
The Revised Character Customization Window
You can still get to the Character Customization window at any time by simply clicking on your character on the Farm. We’ve also added a little reminder icon on the left side of the screen. The window itself has been re-arranged and revised to reflect the addition of Clothing:

The Gender button lets you change your gender as usual. Once you move your mouse over the Facial Features or Clothing buttons, a pull-down menu will appear with all of the different categories for each:

The Facial Features section works much the same as before: you can change your face type, hair, eyes, eyebrows, nose, ears, mouth, skin tone and facial hair types in a variety of manners, all for free.
Gettin’ Some New Digs
The Clothing section is split into two halves: what you have currently in your inventory (which does not count against Gift Box or storage space) for each Clothing category, and what’s available for purchase. Remember that what’s available for purchase also depends on your Gender.
You have a few clothing options already provided in your inventory for each category. Just click on the Use button to change clothes on your character (which you can see on the right). To acquire new clothing you can easily check to see what’s available for that clothing category (use the right and left arrows to scroll through the selections if there are more than three). Most categories have a selection of both coin and Farm Cash items:

If you want to see how it looks on your character, click the “Try On” label. If you just want to buy it outright, go ahead and click on the “Buy” button. Make sure you double-check what you’re doing—you don’t want to accidentally buy something you’re merely trying on.
When you’re trying on new clothes the “Purchase Total” counter on the bottom right shows the total accumulated cost of new clothes you’re “trying” out. You can only try out one piece of clothing per category at a time, so you can’t have five bottoms tallied up, for instance. However, you can have one bottom, one shirt, one shoe, one accessory, etc. selected at any one time. Moving your mouse cursor over “Purchase Total” will also show an itemized total of what you’ve selected:

If you want to purchase all that, just click on the “Buy Now” button and everything will be bought. If you don’t, click on the “Reset” button and everything will be returned back to the market (your clothing will return to the state you were in before you starting trying on clothes).
If you’re just changing your clothes around, the changes won’t take until you click on “Save and Close” at the bottom of the window.
Outfits and Costumes
Outfits and Costumes are essentially one-off clothing choices—when you put it on you wear the whole thing, with the exception that you can change your shoes with an Outfit, but not with a Costume. Typically Costumes will also be tied to Limited Edition sets or themes and only available for a certain period (but not always). Here are some Costumes available for Halloween:

In the Market
You don’t have to go into the Character Customization window to buy new clothes—they’re all available in the Market. We’ve added a new Clothes tab in the Market at the far right. Click on that, and you can see all of the Clothing categories and purchase options. If click on the “Try it on?” label you will be transported to the Character Customization window.
