Luggage and bags:
As there are many cheap buyings in Lahore Plz dont load yourself with heavy load of extra luggage ans bags. When you arrive at lahore just relax for a while and make a shopping trip to a nice shopping mall and buy anything you like...every thing is so cheap....
Clothing/Shoes/Weather Gear: Lahore's climate is very hot in Summer & the temprature goes bit high as well so it is recommended that you should wear summer outfits. Women shouldn't wear skirts or shorts as Pakistan is an Islamic country. Men can wear shotrs & walk around with nothing on their chest. Buy youself a nice Chapal(sleepers shoes) from a market so that you feel comfortable while walking in the streets of Lahore. Don't forget your sunglasses as well.
Toiletries and Medical Supplies: If you are staying in a Three-Five star hotel then you dont need to worry about your toiletries but arrange some relative stuff if you are staying in lesser than that.
Also keep your escential medicine with you as well.
Photo Equipment: You cant beat Europeon Photo equipment like Cameras etc.so take your own camera equipment but buy camera film form Lahore because they are very very cheap....
Luggage and bags:
Everything is available in Lahore. I recommend that its useless to buy expensive things if u are coming from Europe or America. Just come here and go to a nice shopping mall and you will find everything of good quality and less money. This will save you from carrying heavy bags.
Clothing/Shoes/Weather Gear: Its never Too Cold In Lahore. so do bring lots of T-Shirts and Long Shorts. Women Should NOT wear SHORTS but they can wear 3/4 pants. Normal half sleaves shirts are okay. Men can even were nothing on their chest or wear vest only and for lower body, they can wear shorts.
Get some nice comfortable shoes for walking on the streets. The shoes must be durable and comfortable. Keep in mind the temperature and your feet should feel comfortable. I am reminding you about temperature because most of the Europeans and Americans are not use to it. There are all sizes of local 'Chapal's' shoes avaiable and they are quite airy and a person does not feel his feet sweating becaue they are not fuly covered but still nice to wear.
Toiletries and Medical Supplies: hmmmm.... A small first aid kit would be fine with few anti-biotic tablets recommended for malaria, and do keep a water bottle with you. You can easily get good quality Nestle Mineral Water Bottles everywhere in Pakistan.
Photo Equipment: If you are coming from KARACHI to Lahore then you MUST NOT Keep the Battery cells in your hand lugguage. This is enhanced security policy of Karachi Airport that they do not allow any kind of battery in
HAND Lugguage but you can keep them in your other bags going into the aeroplane. Camera Film are NOT Avaible everywhere. Keep two of them or atleast one of them with you everytime. In Posh and modern areas of Lahore you can find nice Photographers and buy any kind of Photography equipment.
Camping/Beach/Outdoor Gear: For Camping there is as such no place in Lahore but you may try it in any park. Better to stay in a cheap 5 US $ Hotel near Lahore Railway Station than a camp!
