Did you know that most makeup tips try to work the eye into an almond shape? It's true. The shape is considered the most flattering and extremely exotic. However, the tips often don't take into consideration those with deep set, wide set, small eyes, round eyes, or heavily hooded eyes. And if you wear glasses? Puh-lease, you'll never find info for that! Except for here that is.

Most of us love the summertime – the sun, the beach, the warmth, the runny makeup... okay, so maybe we don't love all of it. When the weather is hot and you're sweating your face off literally, it is time to readjust your makeup routine so you don't look like a hot mess for the next three months.

The nice folks at Stila sent us some samples so we could try their products first hand. We spread the bounty across two bloggers, Kristen Seymour and Cat Lincoln, who will share their reactions with you this week.

We are heavy eyeliner users, both figuratively and literally, so we've experienced the full gamut of textures: waxy, smudgy, crumbling and smooth. Based on this broad experience, we feel confident in our definitive pronouncement that Stila Kajal Eyeliner is the silkiest pencil we've ever used.

Now before you think we're a pushover for free stuff, let us say that super silky can be a good and bad thing.

As women, we want our mascara to be a macho man -- thick, long, long-lasting, conditioning and waterproof. Okay, maybe that was the wrong metaphor but regardless, we expect a lot out of our mascara but we might not be doing our part in meeting our partner half way.

Here are a few helpful hints to get the best show out of your favorite mascara.

Reese Witherspoon caught our eye in the ads for Avon's new Pro-to-Go lipstick. We thought, that's nice but a bit surprising to see someone so A-list shilling for Avon. Still, a single mom's gotta do what she's gotta do, right?

Then we noticed the incredibly nifty lipstick applicator and all thoughts of Reese flew out of our head. It's designed so that you can flick it open, apply, and flick it closed with just one hand. So cool!

Many of us gals have been the victim of expired cosmetics. Here's the scenario. After seeing pics of that smokin' gloss we used to wear in high school, we rush to our beauty closet only to open the tube to a rank stank that we don't understand. Most beauty products do not have any smell, or if they do, it is very faint. If you start noticing some product BO, it's because that favorite gloss is dying a slow, bacteria-invested death in that dark, tightly sealed tube. Once the product has peaked, it can cause some pretty gross irritations or infections if used. To avoid all of the above, follow these general toss time guidelines.

At first we felt a little, well, superior. After all, we have mad make-up skillz, earned through years of clown faced experiments. And the first item in the gallery was that Sally Hansen nail pen we posted about a month ago. Um, yawn.

But then we were very pleasantly surprised by the rest of the products. Not just easy to use, they are also cool!

The Stylelist Spring Beauty: Blue Eyeliner post made us pull out the makeup kit, ready to go to town. But to our disappointment, we only found old black, grey and brown liners in there.

Clearly we need to upgrade from the neutrals. We're craving some color!

Eyeliner is one of the easiest, fastest and most versatile ways to brighten up your face and be daring. Go bright, dark, sparkling or smoky. Blue can do it all!

Five great blue liners in the gallery give you a flavor of this sizzling seasonal trend. Let us know if you get the fever for some blue!

Ashlee Simpson and Pete Wentz have just proved my hypothesis -- the couple that does their makeup together stays together.

Obviously standing in the bathroom mirror putting on matching eyeliner is a bonding experience for the couple. They've been dressing and doing their makeup alike for a few years now and they've finally decided to make things official. Those two crazy kids announced their engagement last week.

At the gym this week, as usual we were watching What Not Wear. It was standard fare until they got to Carmindy, the so lovely, sweet and dreamy make up guru.

The makeover-ee asked Carmindy to show her how to do a smoky eye. Carmindy arched a perfect eyebrow and responded, "Oh, that's what you want to learn?"

We have to give it to Pete Wentz.

He has been championing guy liner from the very beginning, so it's only fitting that he would become the first man to emerge from the punk scene to create a line of cosmetics specially tailored for all of the guys out there still bumming Dior's crayon eyeliner off their girlfriends.

My sister swears by this fancy Dior Style Liner and badgered me to try it during a recent visit. The tiny silver pot is delicate and pretty and it made a rich, sooty black line on her. One trip to Sephora and $30 later, I was in the club.

So, 30 bucks for .08 ounces, that must have been some liner gold, right? Well...yes and no.

Looking to switch up your look for spring? Maybe you want to find something a little less heavy than regular black eyeliner? You're in luck -- according to The Budget Fashionista, navy eyeliner is the way to go for spring '08.

Models on the spring runway for Narcisco Rodriguez wore an indigo gel liner because, according to Dick Page (the make up artist responsible), "Navy is more mysterious than basic black."

I don't know about the whole "mysterious" thing, but I do like the look. It's just a bit more exciting, adding a little extra "oomph" to your everyday makeup. Plus, it can make the whites of your eyes look a bit brighter (you know, the blue vs. red rule, like when you wear lipstick with a more bluish tone of red or pink, it makes your teeth look whiter -- same thing, only for your eyes).

The Budget Fashionista recommends the L'Oreal HIP Navy Eye Liner Pencil for $8, but I'm sure your favorite makeup brand has their own. Give it a try!

Sit yourselves down, folks. I got a little story to tell first: I can go out without wearing lip gloss or even foundation, but I downright refuse to be seen in public without some sort of eyeliner smudged around my eyes. It's my own pathetic weakness.

So, as someone who would be sworn to a life as a hermit without eyeliner, I am constantly on the prowl for better, longer-lasting pencils. I need something that delivers heavy color, goes on smoothly, and stays on the entire day. For many years, I thought I was just asking too much... Of course, I had started with the drugstore's dollar eyeliners, which came off after five or six blinks. It didn't take me long to learn that there's a reason why some cosmetics cost more than others, and I eventually moved on to better brands, but was, for the most part, disappointed. For example, I used MAC for several years and, although I'm still madly in love with their high-pigment eyeshadows, their long-lasting eyeliner just didn't last long enough.

But I now bring good news: Recently, I received Urban Decay's 24/7 Glide-On Eye Pencil as a gift and I immediately fell in love with the product. It was everything I needed. Obviously, it's so good that I felt the need to share. The pencil in "Zero" (black) is my absolute favorite because it's really strong and dark, but I also gave in to temptation and bought one of the colored ones ("Lust" purple). I have no intention of switching brands any time soon because this is perfect. Give it a try! You won't be let down.

Tip: My favorite way to fully set the eyeliner for extra-long wear is to use a small brush and lightly apply some dark eyeshadow over the line.

By now, you've (hopefully) got your dress steamed of wrinkles, shoes polished, jewelry matched, and handbag outfitted for the holiday parties that have been and still are happening. And even if the holiday parties have already happened, you've still got New Year's.

However, have you done anything about your makeup? The same look you've been doing all fall is fine, if you're going to get coffee with a girlfriend, but you've got to step it up for a holiday party. InStyle suggests you change it up with navy eyeliner. At first, I was skeptical. I've used nothing but black eyeliner and dark shadows to create a smoky look all my life, but the look of navy, especially with plum and bronze shadows, is stunning on Thandie Newton (then again, she probably looks great without any makeup on, too). InStyle used MAC's eyelining pencil in Prussian, which run about $14, but if you don't want to invest that much on something you might not like, try Rimmel's Kohl eyeliner in Denim Blue, which is only $3.19 at drugstore.com
