If you are dieting, it is nice to know where you can get a new blouse as cheaply as the sandwich you didn'tbuy for lunch. Even if you are not dieting, it is handy to know a place where you can buy three blouses for less than the cost of two movies. But you will have to hurry. The Blouse House, which has been a bargain blouse bonanza for the last year or so, is going out of business next Saturday, and until then their prices are lower than ever. Everything will be $2, except sleeveless shells, which will be $1, or six for $5. They still expect to have plenty of tee-shirts, polyester blouses, tank tops, halters and calypso blouses that tie in front. Their sizes range from children's 6 to misses' 36, and they stock maternity tops. They expect to have enough stock left this week to make it a real going away party.
