From a letter to the editor in the Oct. 26, 1906 NYT:

I am sure that Grossmutter Knickerbocker would have held up her hands in amazement, as I did the other day when I saw three articles of lingerie in a new dry goods shop on Fifth Avenue that were market to cost $2,000.

EH.net suggests:

In 2005, $2,000.00 from 1906 is worth:
$45,791.32 using the Consumer Price Index
$35,904.46 using the GDP deflator
$200,254.78 using the unskilled wage
$244,351.51 using the nominal GDP per capita
$862,888.81 using the relative share of GDP

Ouch.
