Needless to say, the Mary Kate and Ashley have influenced my personal style throughout all stages of my life. And while I no longer spend hours scouring LiveJournal communities devoted to MKA’s street style, I can still say I look forward to seeing what creative ensembles (and now, designs) they still come up with. In honor of their 25th birthday today, I’ve chosen their top 6 most iconic trends:

1. Bows (Circa 1986 – 1990, Full House era)

2. Big, Bohemian Earrings (Circa 2004- 2006, New York Minute Era)

3. Oversized Sunglasses (Circa 2005- present)

4. Oversized Tees (+optional Starbucks Venti Sugar-Free Vanilla Latté)

5. Maxi Dresses & Maxi Skirts (Circa 2006 – present)

6. Substantial, Structured Handbags (like the ones from their own line, The Row, above at left)

Whenever I hear of a cool collaboration for charity, my ears perk up, because there’s no better feeling than helping a good cause while you’re feeding your shopping addiction. The latest and greatest: 50% of all proceeds from the sale of this Simeon Farrar for Japanese Red Cross “Kate Mouse” T-shirt will be donated to the Japanese Red Cross earthquake appeal.

How can you argue with that? See more Japan Charity Relief fashion, like the Gucci Japan bracelet,  plus all of this week’s best sales and deals, online sample sales, guide to the best skinny jeans, and best find of the day posts.

It’s officially spring–but after just a few days of dresses, flat sandals and trench coats, I’m already running out of outfit ideas. Jenna Lyons at J.Crew must be a mind-reader, because not only do I want EVERY SINGLE THING on the site, but the sale is an extra 30% off + free shipping if you spend $150 or over with promo code OURTREAT. I don’t need to be told twice, so I’ve picked 5 of the best stuff on super sale for your convenience. Hurry, it ends today at 11:59pm.

Audrina Partridge, Ashley Tisdale, and Kourtney Kardashian all bring new meaning to coat-tails.

Circle cut tee, belly-baring top, “graduated hem” shirt (thanks, Topshop), whatever proper term for this trend may be, we kind of love this new slouchy t-shirt look.  But since the hem in the front is significantly shorter than the hem in the back, these “reverse mullet tops” mean that when you lift your arms up past your shoulders, you’ve got yourself a bordering on Spring Break-worthy party, while the longer cape-style back keeps it all business. Although it may seem counter-intuitive to own a shirt that’s made to look like it’s falling off, this slouchy look just screams comfort chic. Hey, for all we know, these could be this decade’s take on Juicy sweats.

Remember when it was cool to rock a rhinestone belt buckle with the name of your astrological sign? We Cancers could never participate–there’s nothing worse than rocking a belt with a horrible disease printed on it.

So I’m ecstatic to see celebrities like Kim Kardashian (pictured), Megan Fox, and Vanessa Hudgens rocking these Wildfox Astrology Tees, which feature kitschy phrases associated with traits of each sign–Kim, a Libra, is wearing the “Hopeless Romantic” version, while Vanessa Hudgens, a Sagittarius, wore “Happy Go Lucky.”  And good news for Cancers: our shirt says “Imagine,” while the Leos are stuck with “Me First!” Ahh, how the tables have turned.

Cat eye sunglasses are sure to be everywhere this spring, but we have to admit we’ve already picked a favorite: the oversized House of Harlow 1960 Chelsea Cat Eye Sunglasses that their designer, Nicole Richie, wears everywhere. She’s a pretty good advertisement for them, no?

The  House of Harlow 1960 Chelsea Cat Eye Sunglasses ($138) are not available until May 31st, but can now be preordered at Singer 22. And while you’re waiting for them to arrive, check out some other great picks from Ritchie’s boho-glam line.

It doesn’t get more spring than a pale of cream-colored oversized shades, like these House of Harlow 1960 Carey Sunglasses ($121), Wear them with a classic camel trench and flats for a chic Parisian look.

House of Harlow’s 1960 Cassie Sunglasses ($138) are for those days when you’re feeling more rock star than girly. We’d throw these on with a leather jacket and knee-high boots.

A pop of color never hurt anyone, and these red House of Harlow 1960 Nicole Sunglasses ($125) are no exception: they can make any outfit a lot more fun. We’d pair with skinny jeans and a white tee. Voila! Instant, easy style.

Want even more inspiration for spring? Nicole Richie’s Winter Kate line should be your first stop. Then check out our guide to the best sunglasses, and then find skinny jeans, flats, over-the-knee boots, trench coats, leather jackets, and tees to wear your new pair with.

When the Alexa Chung for Madewell line hit on Fashion’s Night Out back in September, there was a ton of excitement–and it sold fast. But as People reported yesterday, there was one little missing piece…a Bat Tunic that was never released. Alexa Chung fans,  it’s finally out.

Fun tidbit: When we talked to Jenna Lyons at the Madewell launch party, she said Alexa doodled the bat during a design meeting, slid her notebook across the table and said, “Does this work?” Even her doodles are frenzy-worthy–the mark of a true star. Get the tunic dress now:
