MAC Vulnerable is a slightly cool-toned, light lavender with a sparkle finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Vulnerable is described as a "soft pearly purple [with a Lustre finish]." It's a light-medium, pinky-lavender with silver sparkle. It had semi-sheer coverage--as anticipated for a Lustre--and a sparkly texture where a lot of the sparkle didn't make it to the lid. There was some fall out during wear, though the pinkish base color lasted for seven hours. MAC Kitschmas (PiP, $21.00) is more shimmery, darker (90% similar).
