I got the blazer on sale from Zara a while ago and the best part is that the leather sleeves are attached making it one piece. Here are some aesthetically similar & affordable options: option 1 option 2
The leather-like pants are from a boutique down on south street seaport (now closed) for $29 but here is the Zara online option
The bag is a great everyday bag from Zara. Similar option here And the Pumps are Kelsi Dagger and I got them online at DSW. Similar option here
Lastly, the big designer steal of this look = the Tom Ford sunglasses. They are actually Mens and retail for $420 but I found them on Amazon for $239
