The clothing retailer’s first-quarter earnings beat expectations. Net income was $184.1 million, or $1.90 a share, up from $120.8 million, or $1.21, a year earlier. Analysts estimated $1.47 a share. Revenue jumped 32 percent, driven by global demand for men’s, women’s, and children’s clothing as well as accessories in the United States. Sales were especially strong in Polo’s stores and in international markets.
