Check out the latest trends
Every year there are new trends in all kinds of clothing and accessories. You can go to a local retail outlet or check online catalogs and read blogs to get an idea of what is trending. When it comes to Valentine's Day however, it is all in the colors.
Stick with bright colors
Pink is a colour that has been associated with Valentine’s Day, particularly for the ladies. You can have your little girl wear something in pink while you may want to stick to more traditional colours when it comes to boys. If you have toddlers, it will be a good idea to have a pink and white outfit. Having a bit of glitter on the girl’s clothing is also not a bad idea. Remember, bright colors are good for the occasion but stick with pastel shades if possible.
Keep it Semi Formal
Make sure that the kids are not formally dressed as it is not an occasion that will require such a thing. However, do make sure that there is some degree of formality and they are not attending the party in t-shirt and shorts. If your relatives are also going to be visiting the party you can ask them about how they are going to dress up their children so that there is a uniform theme if possible.
