Tripping with Chanel

I am planning a trip next month to the big apple. I am trying to pack light to have enough room for purchases that will range from a boatload of beauty products to most likely a coat or two.

Chanel has come out with a beauty kit for the more frazzled world weary traveler. The kit includes the following:

Chanel sleep mask
Hydramax + Active Serum Active Moisture Boost
Soin Tendres Levres Hydra Treatment Lip Care SPF 15
Pro Lumiere Correcteur Professional Finish Concealer in Medium
Inimitable Mascara Multi-Dimensionnel in Noir-Black, and a mini Levres Scintillantes Glossimer in Seashell.

It retails for $175 and comes in a Chanel makeup bag with a removable, full-size clear insert that keeps beauty products safe and easy to spot.
This will help with those frantic moments when you can not locate your mini-skunk brush or MAC Pleasantry blush. It is inevitable that I will have to dump out my makeup bags at least a dozen times during my trip.

Does anyone have any suggestions for packing light when it comes to beauty products? I tend to overpack. I am just always worried that I will need to do a smoky eye at a moments notice.
