No, skillcapes are a members-only feature! You can simply get 99 in a skill then purchase a one month membership to buy the skillcape. When your membership expires leave your skillcape on your back and you will still be able to wear it and do the emote in non-member worlds. If you take the skillcape off in a non-member world the only way to wear it again is to buy another membership.
