Yes, by all accounts that I've heard, the second time around one tends to show earlier.
I like Jennie's idea about the flowy top and pants that could carry over for a while and be used as separates.
Also, I've had a lot of very good luck on Ebay UK purchasing formal maternity clothing for work and such. There are such good bargains to be had, that if you did want to start browsing, you would only need to spend a little. For example, at £1 (+ apx. £5 shipping) per find that you might want to hold at item on reserve-- that might be comforting. I have some lovely Irish tailored suit that I spent that much on... and, at 25 weeks, I still don't fill out the jacket properly! But, I love the suit and am glad to have it in my closet in case a work opportunity occurs at my peak of pregnancy!
Also I got bundles of maternity clothes there... The good news is, Ebay UK just is not as popular as it is in the US, so there's a little less competition overall...
Best, Rutabega
