I ended up wearing something I already owned after a few purchases and some drama. I love this dress, I actually wear it quite a lot, I dress it up or down depending on the occasion. It actually ended up being perfect, it was modest without being too OTT. Zero points for holding your clutch the wrong way round.
Here's the makeup I wore:
Face: Bobbi Brown moisture rich foundation + Bobbi Brown creamy concealer under the eyes. Mac sheer mystery powder applied to T-zone.
Cheeks: Chanel bronze universel, Mac Moon River to highlight + lighter side of Mac Ripe Peach as blush.
Eyes: Mac Carbon e/s in the crease and outer V + Cork e/s to blend it out. Benefit eyebright on inner corners of the eyes. Revlon colorstay liquid liner, Urban Decay 24/7 Zero on waterline and YSL faux cils mascara.
Lips: Mac Oak lipliner, Mac Myth lipstick + Revlon Peach petal lipgloss = LOVE!
On a side note, I picked up Mac "Lazy Day" lipstick, it's simply gorgeous. It's not anything unique but it's just very pretty. It's similar to Angel but a lustre version. I'm seriously loving it!
