NEW YORK ( TheStreet) -- Across the board, August was awash in red, with 21 out of the 28 retailers reporting same-store sales results on Thursday in negative territory. The International Council of Shopping Centers said total same-store sales slipped 2% for the month.

But in each sector there were some clear winners and losers. Here's how TheStreet breaks it down.

TEEN RETAILERS:

Loser: Abercrombie & Fitch ( ANF) once again missed the mark, with August same-store sales plunging 29%, lower than the 23.9% tumble analyst expected. While the teen retailer significantly improved its merchandise selection for back-to-school and lowered some of its prices, shoppers are still hesitant to spend, and instead are trading down to wallet-friendly players like Aeropostale ( ARO).

Shares of Abercrombie sank 4% to $30.82 in morning trading.

Winner: Aeropostale once again was one of the biggest winners, jumping 9% during the month, more than the 7.1% forecast. Aeropostale raised its third-quarter outlook on better-than-expected results. The teen retailer now forecasts earnings in the range of 78 cents to 80 cents a share, up from a prior guidance of 76 cents to 78 cents a share.

The news sent shares climing 6% to $40.96 in morning trading.

DEPARTMENT STORES:

Loser: The luxury sector doesn't look like it will rebound any time soon; case in point Saks ( SKS), which reported a 19.8% plummet in its comparable sales, missing the 14.1% decrease expected by analysts. The company said results were weak across all sectors, and looking ahead continues to expect its results to decline in the "mid-to-high single digit range" for the second half of the year. It projects that its third quarter will most likely be worse than the fourth.

Winner: No surprise, the department store winner was on the opposite end of the spectrum. Value-priced player Kohl's ( KSS) saw a 0.2% increase, better than the 1.7% decline forecast. Kohl's continues to outshine its competitors with exclusive and private-label merchandise.

DISCOUNTERS:

Winner: Off-pricers have been able to use the recession in their favor. Ross Stores ( ROST) reported a 6% incline in August, far better than the 4.3% jump Wall Street expected. Looking ahead the company forecast same-store sales gains of 6% to 7% for September and 5% to 6% for October.

Loser: While BJ's Wholesale ( BJ) managed to beat Wall Street's forecast, falling 6%, less than the 8% decline expected, the company is still struggling due to lower prices at the pump. These declines outweighed gains in food, air conditioners, candy, cigarettes, computer equipment and housewares.

SPECIALTY RETAILERS:

Winner: Gap ( GPS) is making a comeback. Granted, it still saw a 3% decline in same-store sales during the month, but it beat the 7% drop expected by analysts. The specialty retailer has been slowly making its way back into the game with the re-launch of its 1969 denim line, beefed up marketing and refocusing its Old Navy brand.

Gap shares rose nearly 7% to $21.01.

Loser: Children's Place ( PLCE) struggled in August, with same-store sales slipping 8%, a much larger decline than the 3.3% fall expected. As a result, shares of the company were down about 3% to $27.66 in morning trading.
