The ladies wore flower crowns from The Bouqs and noshed on pastel-colored cupcakes and Steve's Ice Cream. Both of the Duff ladies shared a Flipagram slideshow of pictures from the event. 

"Sissy @haylieduff you are the most beautiful sister/mom to be and I love you so much! Happy baby shower day! Thank you to so many for coming and a big thanks to @donatiennela @hannahskvarla @ashleybeverly @thecrowncollective @lowenban @realjoseph #mhbabylove," Hilary, 27, captioned the pictures.
