What kind of combinations are allowed? What kind aren’t?
What items that can be found in the shop are allowed and what ones aren’t?
What effects are allowed, and which are not?
What can happen if someone breaks the Uniform Policy?
1.C §1 - Attire worn in HIA should be appropriate AT ALL TIMES, exceptions being made during special events permissible by HIA.
1.C §2 - Any wearable / set of wearables that covers more than 75% of your character's face would not be allowed; this includes hair, beards, masks, and eyewear. For example, a combination of a surgical mask and a pair of sunglasses would cover most of your face (over 75%), so only either wearable will be permitted in this case.
1.C §3 - You must not be shirtless or wearing little to nothing, ie. Swimwear.
1.C §4 - Anything that resembles another group’s styles, such as raiding groups.
1.C §5 - Copying of another member’s style without their permission is not permitted.
1.C §6 - Styles of offensive manner are not to be worn. This includes that of the racial type. This helps keep HIA a safe place for those easily offended.
1.C §7 - Using any wearable/totem effects (eg. all purple to enable the ghost mode, fire effect, floating effect and more) results to an instant kick. Held effects (eg. Magic Wand, Watering Can, Lightsaber, etc.) are allowed.
1.C §8 - Agents, Security, and Trainers must wear the traditional HIA uniform by stepping through the football gate or through the mannequins in base. A uniform for HC members is also available.
ALL Dress-Code disputes are to be settled by The Chief of Staff team and Directorates/Foundation.
Casual Friday allows all of our members a chance at wearing their favorite items they haven't gotten the chance to wear in base!
Please take note that skins that remove your Habbo's original skin are considered to be functioning as masks. Cat Face, Demonic eyes, Mystic Eyes, Dolled Up Face, Zombie Eyes are permitted. However, RoboBoy face is NOT.
NOTE (Most recent update) Beards and hair are considered wearable. Thus if it’s paired with other items and it covers more than 75% of the face, it is unacceptable.
Certain combinations may be deemed acceptable while others are not - please settle Dress Code disputes with the Chief of Staff Team and/or Directorates/Foundation.
