You do not need to buy a special maternity outfit. Simple clothes often work best. I usually recommend single colours, soft tones and outfits that suit the season and the location.
For outdoor sessions, comfort matters first. If it is winter, dress for winter. If it is summer, choose something you can comfortably walk and sit in. For couples or families, I prefer coordinated colours rather than everyone matching exactly.
You can also use dresses from my client wardrobe. If you want, you can come to me before the session, look through the dresses, try a few on and even take one home with you so you can arrive at the session already dressed and ready. That can make the day itself much easier.
For longer maternity sessions, there can also be time for an outfit change. I always bring a portable changing tent to outdoor sessions, so if you want to change into another dress or outfit, we do not have to depend on finding somewhere private nearby.
Whether we actually plan one or two outfits depends on the session, the location, the package and how the day is going.
If children are involved, it is still possible to change outfits, but I keep it flexible rather than forcing the session around clothing changes.
If you know you definitely want more than one outfit, this is usually better suited to a longer session such as Connection or Full Story, because we have more time.
You can send me photographs of what you are considering beforehand and I can help you choose colours, shoes, layers and anything else that will work with the location.
