Formal clothing chain Men's Wearhouse Inc on Wednesday posted a better-than-expected 28 per cent jump in fourth quarter profit from the year-ago period as it was boosted by a rise in net sales. The Texas-based operator of nearly 700 stores reported net income of $19.9 million versus $16.3m in 2001 with net sales up 1.1 per cent to $390.1m from $385.7m but same-store sales down 2.9 per cent in the US and 5.4 per cent in Canada.
