Just last week I was excited to learn of Alexander Wang's announcement that he would be designing a collection for H&M and while the idea of a high-end fashion designer collaborating with a mainstream retailer is nothing new, it always creates an air of anticipation for fans and fashionistas.   But it seems that every other day there's new word of yet another fashion collaboration (or "collabora-shion", as I like to call it).  Where brands would once use celebrity names and endorsements to advertise their products, it seems that they're now opting to create lines that have been directly inspired or influenced by some form of trendsetter.  These types of collaborations are proving to be really successful; the masses seem to love that their idols may have has a direct hand in creating the product and limited-edition status makes them even more desirable.  Which is why it's no surprise that three more major collaborations have just been announced:

Lorde for MAC

MAC is practically synonymous with limited-edition collections inspired by one celebrity or another (my personal favorite to date being Hello Kitty, of course).  Launching June 5th, MAC Cosmetics' Lorde "collection" is really just two-pieces:  Pure Heroin lipstick ($16) - a deep purple shade inspired by Lorde's signature moody look - and Rapidblack eyeliner ($19) which, quite honestly, I still haven't understood how it will be different from any other black liquid liner.  In any case, I have no doubt these will be in every fashion-forward teenage girl's makeup bag by June 6th.

Proenza Schouler x MAC

For those of us girls who prefer a look that's a bit more classic, Proenza Schouler x MAC has just been released and is available both online and in select stores.  Designers Lazaro Hernandez and Jack McCollough created this line with the overall esthetic of their Proenza Schouler label in mind, and the result is "a collection of confident colour - slick, sleek and effortless with specially designed, limited-edition packaging".  


Kate Moss x Topshop

Kate Moss has made a return to Topshop with her second exclusive collection for the retailer.  The model-turned-designer has come up with four distinct trend themes that reflect her own iconic style: "tailoring noir", "balaeric tailoring", "cocktail hour", and "pyjama dressing".  Launching April 30th, the collection will be available online and in-store at Topshop as well as Nordstrom, Nordstrom.com, and Net-A-Porter.com.  

In honor of the new collection, Topshop has also released a series of videos in which other style icons including Vivienne Westwood and Cara Delvigne discuss their relationship with Moss.
