Wasn't the average American consumer supposed to be out of money (and credit) by now? Apparently not, judging by the sensational retailing results being reported lately. Everybody from Wal-Mart (NYSE:WMT) to Abercrombie & Fitch (NYSE:ANF) had strong results in June. On Thursday, even Charming Shoppes (NASDAQ:CHRS) joined the fold.

Charming Shoppes operates stores under the Lane Bryant, Fashion Bug, and Catherine's Plus Sizes names. About four-fifths of the company's sales are in the plus-size category. For the past couple of years, its same-store sales gains have been anything but plus-sized, but that finally changed in June. Charming announced that comparable-store sales for the five weeks ending July 2 increased by 8%. Catherine's was the real superstar of the bunch, with an almost Abercrombie-esque same-store sales increase of 23%. This was particularly good news because Catherine's was a laggard in 2004 with a 6% same-store sales decrease.

What's more, in a separate press release, Charming raised earnings expectations for the full year. The new guidance is for earnings of $0.69 to $0.73 per share, compared with an earlier estimate of $0.58 to $0.62.

Wall Street liked the news and bid the shares up by about 11% last Thursday. The earnings news probably warrants an even higher stock price, but here's the catch: Charming doesn't expect the strong same-store performance to continue. It's predicting only a low-single-digit gain for the rest of the year.

If that were the end of the story, I would say Charming Shoppes is definitely not worth looking at. But there's more.

The company's financial performance over the past couple of years -- well before June's blowout numbers -- represents a vast improvement and suggests wise management choices. Company execs, for example, have been busy closing and/or relocating underperforming stores. Gross margins and operating margins, meanwhile, have improved, and that has helped free cash flow to expand from $46 million in 2003 to $107 million in 2004. Such an improvement is an impressive feat, given the weak sales trends.

Another positive development appears to be unfolding in the recent acquisition of Crosstown Traders, a catalog-based apparel and gift business. Crosstown has higher gross margins than does Charming's retail stores and will have a positive effect on earnings this year.

The only obvious negative is the same-store sales trends. If Charming Shoppes can coax customers to come by more frequently and spend a bit more, it would likely be capable of continued strong gains in earnings and free cash flow. Investors would certainly have reason to be charmed then.
