Re: What Mac products do you wish you didn't rush buy..
Maybe it as to do with skin tones and undertones for the Alpha Girl BP cause I'm still in love with it, I use it as a blush and allover powder and nothing so far surpassed it for me.

(I'm nc15-20 tho)
As for the products I wish I didn't rush buy:
- All the MES with glitters that I bought (my first purchases from MAC) I never use them: glitter fall outs !!! I have like 5

Family Silver: wow.... those 2 gray are what? one shade darker then the other!? enough said on that. Now I know I can't expect as much payoff with MES as I see in the pans.
- Dazzleglass / Lip glass.... don't throw rock please but with the quality and quantity you get for the price, well I just love the Chanel Lèvres Scintillantes (glossimer) and now the even better Aqualumiere. They are non sticky, some shades are plainly awesome, 30$ but 5,5g. (The Aqualumière are silk soft and non sticky, colors looks deep and shiny) And I hate when I feel the glitters in a gloss, why the hell don't MAC put finer glitters in the Dazzleglass with the price they ask per gram ? I swear that even with Astral (104) witch is a only glitter glossimer, you can't feel any of them, not at all.
Other things I bought from MAC I absolutely love, particularly the pigments; they are what got me addicted to makeup and MAC.
PS: For the Heatherette BP if you don't like the shade you can put a MSF or an other BP or something with the same frame. Someone made a video on youtube: you can easily interchange them, so you'll keep and use the beautiful bright pink packaging
