Goldman Sachs, the Wall Street investment bank that caused a stir when it relaxed its traditional buttoned-up dress code earlier this month, has won a spot of on-trend business: it is one of the lead banks on the initial public offering of Levi Strauss.

The jeans maker that is privately held by the Haas family, filed papers for a public share-listing with the US market regulator on March 11. Shares are being offered at $14-$16, which would raise between $513m and $587m.
