A black blazer and maxi pleated skirt is such a classy combo. Make sure the blazer is longer and looser (aka “boyfriend blazer”) so that when you belt it it has a nice silhouette and is comfortable. All of the items (including the belt) are definitely capsule wardrobe pieces that you can wear separately with virtually anything.
The blazer can be worn with or without a belt or worn open. It can be paired with skirts and pants of all lengths and styles.
A black maxi pleated skirt is timeless and can be worn with anything from blouses and pumps to sweaters and boots.
The black camisole is a great piece for layering or it can be worn on its own since this one has thicker straps.
Finally, another basic is low block heeled pointy pumps with a leather look which match everything and can be worn throughout the day because they’re still comfortable.
