That’s completely up to you. The most important thing is to bring outfits you love and would be happy to see your baby photographed in.
If more than one family member will be in the pictures, it can work well to coordinate colours or tones, but there’s no need to match exactly unless you want to. I also have a small selection of simple outfits at the studio that you’re welcome to borrow.
Some parents prefer very minimal clothing – or even just a nappy – while others enjoy a couple of outfit changes. There’s time during the session to change outfits if you’d like, and I’m always happy to advise if you’re unsure.
