Smash Hit is a repromote - you can compare them at Temptalia in her swatch gallery. I bet it's sheerer, but I don't actually own either of them. I remember not buying Smash Hit when it first came out because i was getting Liquid Lurex, which was similar but more complex. I'll probably grab SH this time, though, since I'm getting a little low on Liquid Lurex and don't have a BU. It's going to look really cool with that pale beige gold lip glass over it.
I hope you're feeling relaxed now, at least
I definitely have to force myself to use the things I buy - if I've bought it, I'm darn well going to crack it open and get some use out of it. But, there were plenty of nice products, especially lipsticks, that haven't gotten the love they deserve. I'm only starting to wear Boyfriend Stealer more lately and Ronnie Red has been seriously neglected lately too.
One thing I jut don't let myself do is switch around to a lot of other brands. MAC's prices have gone up, but I still think they've got the best style to tech to price ratio of the higher end brands, so even when I see something in another line I like (like those adorable Dior shadow palettes with the stars) I just say NO to myself.
One thing I'm not going to allow myself are the shadows if they're too shimmery, because I think we will see these colors in other formulas - there are a few of the new pressed pigments that are similar and by the time holiday rolls around, there will probably be more extra dimension shadows and who knows what else.
