In celebration of National Lipstick Day tomorrow (Saturday, July 29th), MAC Cosmetics will be giving out free, full-sized lipsticks – while supplies last – at any MAC store or retailer.

Apparently, there’s no catch and no purchase is required beforehand.

Make sure to get there early, tho, since there will likely be long lines as the turnout is expected to be large.

We suggest you have a color in mind before you go. Click here for ideas… and there are so many choices from gloss, ombre, nudes, mattes, stains and more. Bestsellers include Ruby Woo and Diva. For something more neutral, try Honeylove or Dearly Beloved.

UPDATE: We stopped into the MAC store on Broadway in Soho to ask about today’s sale. Staffers told us that the 28-collection Colour Rocker collection (pictured above) will be the major part of the give-away as well as a “few” other shades. It appears that not everything in the brand’s line will be up for grabs.

If you do partake in the giveaway, we’d love to hear from you. Let us know what you came out with!
