Its up to your style .. your all saying you go for the subtle looks .. WHY! be urself ..
Im in school and i wear every colour of the rainbow… i use shimmer white right up to my eyebrow .. then i use a bright colour at the end to match my clothing or jewellery .. any colour is good for any time .. i personally think if you feel like being sexy use black and white and the more bright colours for day to day life .. eyeshadow is what shows off your personality.. i have seen soooo many people looking like crap for doing it wrong, but i have three sisters who taught me plus ive learnt stuff from beauty magazines ..
Neve ever ever ever ever ever ever use eyeshadow without mascara or i will personally jump through your computer screen and force you to wear it .. It looks terrible without it unless you have long jet black lashes .. which people rarely do..
