Luggage and bags: If you go into the museums or art galleries and you are wearing a small rucksack they ask you to wear it front ways, instead of on your back.
Clothing/Shoes/Weather Gear: Make sure you wear comfortable shoes, paris is very dusty on the ground so don't wear any thing to fine.
Toiletries and Medical Supplies: Drink plenty of bottled water in warm weather.
Photo Equipment: Not allowed flash on cameras but you are able to take photo's in the galleries.
Luggage and bags: Light, depending on how far you are travelling from. Guys don't do yourselves in, have wheels, but remember not all metro stations have escalators and lifts, in fact a lot don't so if possible pack very lightly and have rucksacks / hiking packs so that you can carry most of the weight on your back. This will leave your hands free to negotiate the stairs!
Clothing/Shoes/Weather Gear: Comfortable walking shoes for walking around town. If you want to dress for dinner in a swanky restaurant, then make sure you have something to go out in. Thin stiletto heels for ladies can get stuck in ventiliation shafts for metro stations that are all over Paris streets, as cobbles can break/ damage heels and ankles. Keep shoes as stable as possible unless you plan on getting a taxi everywhere.
Toiletries and Medical Supplies: You can find everything you need in pharmacies, though if you need something special, make sure that you bring it with you to avoid the shock of need a doctor's prescription for it. You won't find medication anywhere else but in a pharmacy, unlike in the UK or US where you can find paracetamol in supermarkets. The French are also picky about over the counter medication. Even high dose iron tablets need a prescription, in the UK and Canada I have seen 200mg ferrous sulphate tablets, but in France 80mg was the highest I saw.
Photo Equipment: All can be found here in camera shops.
Camping/Beach/Outdoor Gear: For Paris you won't need this kind of stuff
Luggage and bags: I carried a comfortable zipper-top tote bag on my shoulder for shopping and sightseeing. It started out fairly empty in the beginning of the day (water bottle, cameras, map), and my purchases could fit in that bag as the day went on and I didn't have to carry around lots of individual bags from the shops (which can get lost very easy). Not that I bought a lot, but it was much more convenient. I didn't have any problem with safety or pickpockets.
Clothing/Shoes/Weather Gear: I do not like to stand out as "The American Tourist", wherever I go. It was spring, and I brought a black wool blazer that I could layer under, a colorful scarf, a couple of pairs of trousers (no jeans), one button-down shirt, a few layerable cotton tops, socks and underwear, and comfortable black shoes. And a compact umbrella. That's it! I wore most everything more than once which was fine.
Toiletries and Medical Supplies: Tissue for the public toilets, moleskin or band-aids for blisters from walking, aspirin in case you get a headache from too much wine, and Pepto-Bismol or antacids in case you overindulge on the great food!
Photo Equipment: I kept two cameras, one loaded with color film and one loaded with black and white film. I took some exquisite b&w shots of the Venus de Milo and the Louvre pyramid, of Notre Dame, and the bustling streets. Paris is a great place for black and white photos!
Miscellaneous: A journal for documenting details of your trip and also the many photos you will take!
Luggage and bags: Paris is one place I prefer my backpack convertible bag (Campmor Essential Carry-On) to my wheeled bag (Rick Steves Wheeled Bag), because of the stairs! Each time we've visited Paris, we have been in a hotel with a small lift--not large enough to accomodate a large group and oversized luggage. Taking my own bag to the third floor, I would have preferred not to have to lug my heavy wheels. My canvas bag would have been a much better choice. If you are staying at the Ritz, I suppose this is not an issue. For those of us, enjoying a two or three-star hotel, however, packing light is the thing to do for Paris!
Luggage and bags: It always happens sooner or later: you will wish you had a large bag to carry your daily items. Instead of realizing this after you arrive in Paris pack either a backpack or a tote bag in your luggage or carryon. It's a huge lifesaver when you end up buying things you didn't expect to buy. And you can use it as an additional carryon bag if it's necessary. But make sure you are within your carryon baggage allowance first!
Luggage and bags: My only tip is, if you know you're going to have to cross Paris by Metro and you have to change trains, try to take a shoulder bag or rucksack instead of a proper suitcase. There are loads of stairs to climb/ go down and the turnstyles are quite awkward, so it's really not fun dragging/ lifting/ dropping a heavy suitcase all the way.....here speaks the voice of bitter experience!!!
Clothing/Shoes/Weather Gear: One question that appears in the Paris forum all the time is What should I wear? It seems to me that people stress about this loads before they come to Paris when really there is nothing to worry about!
Paris is a Western capital city and like all capital cities you see just about every type of person on the street, from the conservative businessman/woman to the punk revivalist and everything that's inbetween.
No one's going to look twice at you and if they do, so what?!
Other than that just apply your normal common-sense dressing rules you would follow back at home... if you're going to a church, don't wear a micro mini skirt and revealing top...if you're going out to a nice restaurant, don't wear shorts and battered old trainers!
It really is that simple.
Just relax and enjoy your time in Paris!
Toiletries and Medical Supplies: No need. One thing the French are not lacking is Pharmacies!
Luggage and bags: A daypack will be useful for carrying guidebooks, cameras etc, try and bring a bag that you can wear on your front or over your shoulder.....basically so that you have you eye on it at all times...esp on the metro!
Clothing/Shoes/Weather Gear: We visited in August and although the weather was warm it lashed rain!
So I reccommend either a light rain coat and/or an umberella!
Toiletries and Medical Supplies: You can buy most things in such a big cosmopolitan city like Paris!
Photo Equipment: A good camera - pref with zoom....those buildings have so much detail.
Miscellaneous: Along with the other guidebook I already mentioned which had really good maps in it, I also used the AA guide to Paris.
Luggage and bags: bring a bag that is easy to carry around and have an empty bag to fill with all your new clothes!
Clothing/Shoes/Weather Gear: sort out all the clothes you would like to take, then only take half of that pile!
Toiletries and Medical Supplies: you can get anything and everything you need in paris so why not try some french shampoo!
Photo Equipment: as little as possible!
Luggage and bags: Depends on your willingness to carry more than one bag... at least when you arrive in Paris.
You can buy an extra bag if you need it !
Clothing/Shoes/Weather Gear: Depends on the season !
Toiletries and Medical Supplies: Bring your doctor's prescription if you need to buy special medicine.
Miscellaneous: If you forget sometinh : don't worry !
There are supermarkets in France too !!!
Luggage and bags: It,s very useful to have with you small bag or shoulder bag to have in it camera ,Map,coin, pen,s and jacket
