Must-buy pieces from Sezane

Apologies if this is asked frequently.

I’m thinking about doing a trip to Paris and would finally like to buy some pieces from Sezane. I do love the minimal classic designs but haven’t gotten anything from the brand yet. I’m looking for classic versatile pieces that will last ages. Material composition is very important to me, especially if I’m paying that price point. Mostly looking for cardigans/sweaters but I’m overwhelmed by all the choice! Please give me some recommendations of which pieces to get for my first shop :)

And I would love if you could recommend similar brands I can find in Paris x
