There are a few pieces every lady should have in their wardrobe:
Jeans, well fitting skinny jeans and a bootcut.
I love my Joe's Jeans bootcut, and Ben Sherman skinnies.
Black dress pants. I'm loving the J.Crew Minnie Pant- and the tan are perfect chinos.
Pencil skirts, black is a easy choice, but a colorful print or solid can pack a lot of punch into a wardrobe.
Oxford button-downs. Love the soft cotton ones from RL Rugby. Too bad they are going out of business!
Wrap dress. The dress that made Diane Von Furstenberg. They go with anything, are super comfortable and transition easily from the office to cocktails.
Whatever the shape that fits you best, you can never have enough little black dresses
Cashmere sweaters. In as many colors as you desire, v-neck or crew. I love J.Crew's Cambridge Cable sweaters- they come in both crew and v-neck.
I actually have a cardigan addiction- I have 3 black cardigans, and a rainbow of other colors. So why do I pick black? It goes with everything (expect navy).
Navy blazer. A classic school-boy blazer goes well with both casual and dressy occasions. They look great thrown over a dress.
Leather belts. Make sure they are well made in a nice leather. You should have one in black and one in brown.
Trench coat. Think Burberry styling. I have one from London Fog with a cashmere liner that I love.
Peacoat. No matter where you live, this is perfect for winter.
Riding boots. The Classic Equestrian style (think Ralph Lauren and Burberry) never goes out of style. It is classic and timeless and always perfect for fall.
CFMN boots. Black boots that say Come F*ck Me Now. Sexy and practical.
Black ballet flats. Always and forever. I wear through them so quick that I might as well buy these Old Navy ones in bulk.
