POLONIUS      Costly thy habit as thy purse can buy

But not expressed in fancy – rich, not gaudy;

For the apparel oft proclaims the man

And they in France of the best rank and station

Are of all most select and generous chief in that.

Neither a borrower nor a lender be,

For loan oft loses both itself and friend

And borrowing dulls the edge of husbandry.          (1.3.69-76)

More advice! Costly thy habit as thy purse can buy—good clothes are a worthwhile investment, you get what you pay for—but not expressed in fancy; don’t be too slavish a follower of fashion, rich, not gaudy. You’re aiming for elegance, classic style, a capsule wardrobe in neutrals, a well-cut pant in a lightweight wool blend, a cashmere knit—for the apparel oft proclaims the man. People WILL judge you by what you’re wearing, and you need to make a good impression: they in France of the best rank and station are of all most select and generous chief in that. You’re going back to Paris, fashion capital of the world: the French understand clothes, style, taste; they’ll sniff out a knock-off in a heartbeat. You need to get it right. (And, please, don’t get a tattoo, or one of those piercings, at least not where I can see them.)

Moreover, neither a borrower nor a lender be. Don’t get into debt! And don’t lend money to others either, it strains your friendships even if it doesn’t unduly pressure your finances, or if it’s eventually repaid in full (unlikely)—for loan oft loses both itself and friend. Don’t go there! And borrowing dulls the edge of husbandry: if you rely on credit to live, you’ll never learn how to manage your money, how to live within your means.

Nearly finished? Perhaps partly Polonius just keeps talking so that Laertes can’t leave?
