Most department stores now have maternity clothes as regular stock. There are also specialist companies that sell these, usually by mail order. Look in phone directories (yellow pages) or ask in shops for details of these. However with current fashion trends, you should be able to get loose, baggy clothes which are not specifically maternity. Anything which is comfortable is the thing to focus on. Remember too that you will get bigger so don''t buy a lot of things at the start but buy as you need to ensure the clothes you buy actually fit when you come to need them. This particularly applies to bras.
