These are the outfits and colours that I rotate between currently :)
Guidon Bearer - 870 TibiaCoins from the Store, I love the way the outfit looks and how its holding that massive flag!
Festive Outfit - Obtained from the First Dragon (only during Tibia's Anniversary), love the fact that its only obtainable during a short period every year, making it somewhat rare even though its not too hard to get.
Entrepeneur - 750 TibiaCoins from the store, I simply just love how this outfit looks, I only use the one addon though. Slightly dissapointed that they made the outfit available for everyone in the store but hey thats life!
Discoverer - Measuring Tibia Quest, not everyone can be bothered exploring Tibia, searching for those pink circles. I adore this outfit, The outfit just screams adventure/hiking and I love the little backpack and everything, Just waiting for the second addon to be available so I can finally complete it :)
