                 JoS. A. Bank Clothiers Reports 34.0%
Increase in December Sales; Comparable Store Sales Gain 20.7%; Company
                    Raises Earnings Guidance Again

    HAMPSTEAD, Md.--(BUSINESS WIRE)--Jan. 5, 2006--JoS. A. Bank
Clothiers, Inc. (Nasdaq National Market: "JOSB") today reported that
its total net sales for the fiscal month ended December 31, 2005
(fiscal December 2005) increased 34.0% to $91.1 million, compared with
$68.0 million in fiscal December 2004. Comparable store sales
increased 20.7% and combined catalog and Internet sales increased
34.1% in fiscal December 2005, when compared with the same prior-year
period. The comparable store sales gain represents the third
consecutive year that JoS. A. Bank Clothiers has posted double digit
comparable stores sales gains in the fiscal month of December.
    The Company also noted that it expects earnings per share for the
fiscal year ending January 28, 2006 (fiscal year 2005) to at least
meet the consensus analyst estimate of $2.20 per share, representing
at least a 28% increase when compared with earnings per share of $1.72
in fiscal year 2004. The Company also noted that its financing remains
strong as there are currently no outstanding borrowings under its $100
million credit agreement. In addition, the Company's cash balance as
of January 4, 2006 was approximately $8.5 million more than its cash
balance at the same date last year, despite investing in the opening
of over 50 new stores and building its inventory in certain key items
during the current fiscal year.
    "We are very pleased with how well the JoS. A. Bank brand
continues to perform and deliver record-breaking earnings for the
Company and its shareholders," noted Robert N. Wildrick, Chief
Executive Officer of JoS. A. Bank Clothiers, Inc. "We have pursued a
number of initiatives in recent years designed to establish JoS. A.
Bank as the premier menswear brand in America, including a
brand-building media advertising campaign that began in November 2004.
We believe we have made great progress towards this goal, as evidenced
by the sales strength we have seen during key gift-giving periods.
While weather and other factors make it difficult to project sales and
gross profit margin in January, we expect to at least meet the
consensus analyst estimate of $2.20 per share for fiscal year 2005."
    While sales have increased in all merchandise categories during
this year's holiday season, particular strength has been noted in
blazers, sportcoats, sportswear and other key items the Company
invested in this year.
    Total net sales for the eleven fiscal months ended December 31,
2005 increased 24.4% to $433.8 million, compared with $348.6 million
for the eleven fiscal months ended January 1, 2005. Comparable store
sales increased 10.0% and combined catalog and Internet sales
increased 24.9% in the eleven fiscal months ended December 31, 2005,
when compared with the same eleven fiscal month prior-year period.
