People of Tuzla, like in the rest of Bosnia, are very fashionable. Espeically women... So if you are going, make sure you have some nice outfits to wear even if you are just going to a cafe during the day. Obviously nothing too fancy like prom gowns, but some nice pants, skirts, dresses and shirts would do. Please try to match!:)
Just regular shoes are fine, but white sports socks with anything but sneakers are a no-no, for women and men alike. (unless you wanna be called a peasant:)
Toiletries and Medical Supplies: You actually don't need to take any, since you can find a lot of Nivea products as well as other companies' products in almost every store and at the open market as well
As for the Medical supplies, there are a lot of pharmacies, but if you need some alergy medicine, bring your own, since Bosnians are not big on alergies:)
Photo Equipment: You can buy film in any photo shop
Camping/Beach/Outdoor Gear: Hiking shoes would be nice when going into the hills or to the lake
Miscellaneous: Bring a swimming suit if you are going to swim in the pool or at the lakes, since the selection is not that great if you want to buy one, God knows why. Also, if you plan on buying clothes in Tuzla, also plan on wearing size 10-12 or less, since most of the nice and fashionable stuff you see will be in very small sizes.
Luggage and bags:
I take one suitcase filled with my clothes, and a carry-on backpack with essential items. Make sure your backpack is fairly spacious as you might want to wear for a while if you're to walk around a lot.
Clothing/Shoes/Weather Gear: Definately wear comfertable shoes, if you want to have the best time, plan on doing a lot of walking. Besides, nothing is that far-away anyway. In the summer, wear shorts and anyold t-shirt. Pack a parka or something similiar in case it starts to rain. In the winter, just bring your standard winter clothing. (Although summertime is by far the best time to visit Bosnia.)
Photo Equipment: A camera is essential. Tuzla is a great place for taking pictures. Unless you're really into B&W, I would bring color film. Batteries and film can both be easily attained.Batteries can be found at almost any of the kiosks around town, while film should be bought at a photo place. You're most likely to find Fujifilm or Agfa, I haven't seen too much of Kodak.
