The fifth annual Clothe-A-Thon to provide new and used serviceable clothing for underprivileged schoolage children will be held this Saturday.

The program, which is sponsored by the non-profit D.C. Council on Clothing for Kids, Inc. and WJLA-TV, will be broadcast on Channel 7 from 11 a.m. to 8 p.m. Saturday.

Throughout the program, monetary pledges will be solicited "to provide clothing for needy children in order to help them to remain in school and to participate in school activities," according to Annette C. Reid, president of the all-volunteer clothing council. The clothing is a available to children in the entire metropolitan area.

While the Clothe-A-Thon is being aired, people can also bring new and used serviceable clothing to the Seven Corners Shopping Center in Virginia, Montgomery Mall in Maryland, and WJLA-TV, outside 4461 Connecticut Ave. NW, in the District. The children's clothing can also be dropped off at any fire station in the District during the Clothe-A-Thon.

Reid stressed that money raised through the Clothe-A-Thon is almost entirely directed "to buying clothing for children . . . we try not to put our finances into a lot of personnel." Checks can be made payable to Clothing For Kids, Clothe-A-Thon, Inc., and pledges can be made through Channel 7 during the broadcast or mailed directly to the D.C. Council on Clothing for kids at Box 2676, Washington, D.C. 20013.

The annual Clothe-A-Thon is the culmination of the council's clothing drive, which involves area businesses and federal and district agencies in setting up collection boxes for employee contributions.

The clothing is distributed at The Children's Boutique, a six-room house converted into a store-like setting at 2728 Sherman Ave. NW. Parents can get clothing for their children at the boutique if they have a referral or letter "from any legitimate agency or organization in the metropolitan area," Reid said. Schools and welfare agencies provide most of the referrals.

Parents who are interested in getting free clothing for their children can get letters from agencies and call the boutique at 232-0700 for an appointment. The boutique is open weekdays from 9 a.m.to 4:30 p.m.
