Just in time for your fashion week travels, a new e-commerce site is here to make sure you get through the airport security line without having to tearfully chuck any of your favorite beauty goods -- or pony up cash to check your overflowing bag.

Founded by beauty junkies Kate Duff and Alexi Mintz, 3floz.com, which launched this week, is hoping to become the destination for the hautest of beauty and personal care products in TSA-friendly sizes (aka 3 fluid ounces or less).

"We were traveling a lot for work and I'm the type of person who takes everything with me," explains Duff, who met Mintz while working at Archipelago Botanicals together, of the beginnings of their company. "I would have to check two giant suitcases to fit all of my full-sized products and Alexi came up with the idea of the site. With TSA getting stricter and the cost of checking bags going up, we think this is the right moment."

Some of the brands signing onto the launch include Go Smile, Yes to Carrots, Malin + Goetz, Ole Henriksen, Ted Gibson and Anthony for Men, among others, with more brands coming soon.

"All the brands we're launching with we have been using for years and years," says Mintz. "Especially the men's products. And I really hope we can be a part of closing that gap so that both men and women can use the same products."

As for their own travel must-haves, Mintz says, "I am obsessed with the Yes To Carrots facial towelettes, the bergamot body wash in the Malin + Goetz essentials kit and both Kate and I use this glycolic cleanser by Anthony for Men."

Duff, on the other hand, is "100-percent in love with the Dr. Hauschka lipbalm, Go Smile and Jonathan dirt spray. It gives your hair great volume."

3floz.com is a smart innovation that will go head to head against the travel sections of major online retailers like Sephora.com's Beauty To Go and Ulta's Travel Sizes.

Not to mention, 3floz.com is a great way to sample some new products at a fraction of the price of their full-size counterparts.

Now that's plane pretty.
