I'm 12 weeks now and just starting to see that I'm probably going to need slightly...erm...roomier undies at some point in the next few weeks.

I wear a lot of fitted/jersey dresses, skirts and skinny jeans and basically only wear seamless underwear as a result as I HATE VPL.

I also don't really like or wear thongs. So I'm looking for bikini or hiphugger/boy brief type seamless panties.

I have been wearing almost exclusively the Victoria's Secret Body by Victoria No-Show panties for years
(here are the bikinis: http://www.victoriassecret.com/panties/no-lines-and-seamless/no-show-sexy-bikini-panty-body-by-victoria?ProductID=21909&CatalogueType=OLS), but they're pretty pricey at $11/pair even when bought on special.

Would you guys just go with the underwear you already know and love and just buy a size up for pregnancy?

Or do you guys have any suggestions of other seamless/no-show (non-thong) undies that you like for pregnancy? Bonus points if they're not super expensive!
