With my first, I spent money on some ugly maternity clothes that I never even wore much. With the trends gearing towards billowy blouses, empire waists, loose fitting knit tops etc, I'd rather buy normal clothes (maybe even in a bigger size) so I can wear them again. The only things you really need in maternity are pants and jeans. But I bought some pants from Zara on sale ($300 each) in a bigger size and I just use a rubber band or belly band to secure it.
