Just some ideas:
- a generous neutral/browns es palette
- a colored es palette
-a blush palette
- a transparent powder
-a wheel concealer
- lightest and darkest warm and cool foundations
- a nude lipliner and a red one
-some water resistant eyeliner black, brown, grey, white and nude
-mascara and lipgloss wands
-hand sanitezer, brush cleaner, moisturizer(graftobian has one with sillicon , so you can skip the primer if you use that)wipes,etc, etc
Try to think about the colors that are most flattering for most skin tones to take with. Definitely use sample containers for things that are in bottle containers because they are heavy to carry around.
