Whether originally intended as designer maternity wear or just cleverly adapted, there's no doubt that Jennifer Garner has secured her maternity style status looking flawless in her "pink" YSL bubble dress and Valentino shoes at Monday's Pink Party which benefits the Cedars-Sinai women's cancer programme!

The flirty shaped bubble dress is a real favourite with modern designers and although it can be tough to wear as a civilian, particularly for us gals with wider hips, it makes for excellent maternity wear and is perfect for showcasing a good sized pregnancy bump.

If Yves Saint Laurent is not an option for your wallet there are still plenty of loose bubble styles around on the high street.  For an alternative daytime look, think pretty cardigan, opaque maternity tights and a wedge heel boot this autumn.
