Hi, alot of people have suggested to me to try belly belts first before buying maternity clothes. Only problem is I have no idea what a belly belt is and haven't been able to find them anywhere in any of my local shopping centres. Even alot of salesgirls don't know what i'm asking for, lol. Hopefully someone will be able to help me out with these questions.

What is a belly belt ?
Where do you buy them from ?
What do they normally cost ?
Are they a better alternative to buying maternity clothes ?

Thanks so much for your help
Sharon
