Curious . . Help please

Okay so my baby showers on Saturday ( oct, 25 )  I'm having a girl. Well I went shopping with my mom to look for a dress to wear that day, anyways my mom picked out a blue dress , it looks really nice. I'm just curious is it weird to take a blue dress even tho I'm having a girl n mostly the things are going to be pink ? The dress looks like the one in the left but the colors like the one in the right, what you girls think ?
