The most important thing to remember about what to wear is to be yourself! Find something that fits you and your child's personality. I recommend trying to find outfits that are unique but compliment one another.
For children, I recommend good fitting clothes in bolder colours. For babies and toddlers, you want to hide any sign of a diaper, put a onesie on underneath the outfit.
For adults, avoid clothing with logos that will distract or date your photos. Avoid all white or all black “matchy matchy” outfits.
Remember that accessories (scarves, jewellery, headbands) can also add to your overall look.
Also be sure to try on your outfit before your session! There’s nothing worse than finding out that something doesn't fit an hour before your session time!
