Black Leather Jacket (All Saints "Hawks Leather Biker Jacket" $630)
This list is in no specific order however, a black leather jacket has to be my favorite of closet essentials. To me no piece works as a better confidence boost. A black leather jacket with a swipe of red lipstick is the quickest way to feeling like a total bad-ass. You don't even have to worry about doing your hair or spending a million hours on your make up, just throw on your jacket over a tee and you're good to go. It's perfect for those days when you have five minutes to get out the door. It works day-to-night all year long. So all in all, there is no reason for you NOT to go buy a leather jacket immediately.
LBD (Alice + Olivia "Strapped Back Dress" $198)
You didn't really think the LBD would be left out of this list did you? I know, I know, you've heard it a million times. You're mom has told you, style.com has told you, Vogue has told you, and so has basically every other woman and fashion resource you have ever encountered. An LBD is a MUST. I don't even know how it would be possible to function without one in your closet. They work for everything from office parties to date night to nights out with your girls. There is one important key to the the perfect LBD though and that is to keep it simple. The point is to invest in a dress that is versatile. Black can be work anytime of the year and simplicity works for a million different occasions. It there is one thing you get from this list it should be that as a woman you must own a LBD.
Black Booties (Steve Madden "Wantagh" $170)
Booties are an extremely important item to have in your wardrobe. Ideally both a black and brown. however, seeing that most often black matches I felt that black booties trumped brown on this list. Just like the LBD, don't try to get to crazy with your booties unless you already have a simple pair. Buckles and studs are great don't get me wrong but, they just don't always work. I promise you will regret spending hundreds on a pair of decorated booties when you realize there is no way you can wear them with half the things you own. Keep it simple. I wear my black booties almost daily, they work with honestly everything.
Black Skinny Jeans (Madewell "Skinny Skinny" $115)
I can't not emphasize this enough: you absolutely have to own a pair of black skinny jeans. No excuses, you absolutely must have at least one pair of good black skinny jeans. They're less casual than dress pants but, dressier than blue jeans. You really should own them for that point alone. If you need more convincing, also note that they will match just about everything.
White Tee (Madewell "Tailored Tee" $79)
I'm sure by now you've caught on to the theme here: basic, basics, basics. A white tee should be a no-brainer. It's a staple piece in every one's closet. You can wear it alone, under a jacket, with a blazer, you name it and a white tee will match it. What I love about this Madewell tee is that it is a little nicer than average, giving it a little more versatility. Plus, Madewell tees are unbelievably amazing.
Black Pumps (Kate Spade "Licorice Too" $298)
You had to have seen this one coming. Every woman on the planet must own a pair of black pumps. I don't care if you are the sports girl in the world. You will need a pair of black pumps at some point. Most likely you will need them on numerous occasions. You'll need them at the office, for an interview, on date, for a night on the town. There is zero chance of avoiding situations in which black pumps are a part of the uniform. These are and item to splurge on.
White Button Down (Aritzia / Babaton "Dax Shirt" $85)
This is really just a more formal version of the white tee so, copy and paste what I wrote there. This is just a little bit nicer version. Get it. Wear it. Love it.
Black Blazer (Zara "Long Blazer" $80)
This is probably the most important piece on this list. Just like the black pump, there is no escaping the fact that you need a black blazer. First of all you will absolutely need one for a job interview at some point. A black blazer is the core of any professional wardrobe. They aren't just for the work place though. There is nothing chicer than a blazer for a night out on the town. Glam it up and it can be totally sexy. I suggest trying on a blazer before you purchase it though. There are too many different fits to just pick one out of no where.
Black Ballet Flats (Tory Burch "York" $195)
These are more a practicality piece. If you are anything like me you would chose even the tiniest heel over flats any day. Truth of the matter is, you really do need a pair. Especially all you city-dwellers out there. You do not want to walk blocks to work or back home from the bars in 6 inch stilettos. I promise you you will regret it and your feet will hate you for the rest of eternity. Give your heels a break and at least throw a pair of these into your back for your commute and throw your heels on at the office.
Basic Turtleneck (Aritzia / Babaton "Nicolas Sweater" $165)
For are you who think turtlenecks are too old for you, I was in the same boat once. Until I realized that turtle necks are actually a gift from god. They really are a need. I personally prefer the loser necked one. Not only are they more comfortable but they're a little funkier if you're worried about looking like a grandma. But just like the blazer, I suggest trying them on in person. To all you doubters, at least give one a try.
