Wow! Many of you ladies are super organised!
I try not to carry a heavy bag as it is not good for my back. So in my purse I just keep a combination foundation/powder, for touch ups if needed, and two Clinique Chubby sticks, for on the go repairs! But in my office drawer I also keep mascara, eye liner, blush and a hairbrush, in case I need them. I have found this more necessary since moving to a warmer climate, where I might need to touch up sometime in the day, especially if there is a shower of rain!!!
I also travel quite a bit, and I must say I keep a small bag of gift with purchase stuff, so I can pack quickly and efficiently. I don't duplicate hair products though, and that always seems to require a bigger pack...

For 6 years I had a permanent locker at one of the gyms where I worked out and it was stocked with full size duplicates of products I used as well as a 'fro pick (I have curly hair). Now I schlep a kit with mini decanted products back a forth. I have 2 different kits depending of the place and type of workout I'll be doing, and what the cleanup will entail. (I almost always have to shower, but I don't always have to wash my hair.)

At work I keep a toothbrush and toothpaste, a nail scissors and file, a mini first aid kit, and a tube of lippie.

I sometimes duplicate lip items, if they are drugstore brands. But 99% of my makeup are prestige brands, so it's too expensive to duplicate. Plus, I stick with the life cycle recommendations, discarding when they're past time.

The only thing I retouch during the day is lips, anyway. I keep all my lip things in a bin by the door, and put the one I'm wearing that day into my purse. I take it out when I get home.

Before I had a home gym, I did keep a small makeup bag with some drugstore items in my gym bag, as well as a bag of toiletries for showering.

Deborah and others -- my favorite organizer is a PurseN. I was able to find one in person to check it out, and have been using it for several years now. Love it! http://pursen.net/collections/.....rts-medium

Thanks so much to everyone for contributing your experience to this thread. Some of you are a great deal more organized than I am!! I am going to think this through a bit more and decide.

I will say that the contact lense container was the most original idea to me!! I used to use them (now I use dailies on the rare occasions I wear them) and may still have some.

As I travel overnight 1-2 nights every week, I have a smaller version of my home makeup kit that stays in my suitcase.
One of the cup holders in my car is crammed full of lip sticks/glosses.
I keep a powder and kabuki brush and a wide tooth comb in my car too.

Like LisaP, I have lip glosses stashed on every floor of my house...totally addicted.

Because I don't have to go to an office anymore, I've simplified. The only make-up duplicates I carry in my purse on a daily basis are tinted lip balm and a concealer. When I leave for longer periods/social activities I have a small make-up bag with lip, concealer, compact powder and eyeliner for touch-ups. I also have a comb, travel hair spray and a few hair bands.

I do use a purse organizer but it only fits in my medium to larger size bags. I'm wearing more smaller cross-body and clutch styles so it's cumbersome keeping organized.
