Nail polish chips easily when you're carrying luggage, making your manicure unkempt. Opt for pale neutrals such as nudes, light pinks (try Dior Vernis in Nude Chic) instead of darker shades so any chips won't be readily noticeable. Or get a 'buff' manicure -- ask your manicurist to buff your nails to a shine instead of applying varnish.
