Mirroring the trend in mens fashion, a kids tuxedo is more expensive than a kids suit of equivalent quality. There are two main reasons for this:
A tuxedo can be set apart from a suit by the presence of satin detailing (on the lapels, buttons, and lining along the side of the trousers). Satin is a premium fabric that is usually quite costly.
A tuxedo ensemble must be completed with several accessories (including a cummerbund, waistcoat, suspenders, and a bowtie). These added components also contribute to a heftier price tag.

As the most formal of attire, a tuxedo should generally be reserved for black tie or white tie events. For children, these occasions could include a formal dance, family dinner party at a formal restaurant, or a wedding. If there is any confusion over the suitability of a boys tuxedo suit for a certain occasion, it’s best to check the dress code on your invitation or the venue’s website.

This elegant evening ensemble has roots in Great Britain, and was originally reserved for formal social events held after 6pm. Introduced to America in 1886, its popularity increased and it evolved into a less formal alternative to the dress coat. The tuxedo has remained virtually unchanged for more than a century. It is easily distinguished from a suit by the presence of satin (on the lapels, buttons, and lining along the side of the trousers) and the accessories with which it is worn (cummerbund, waistcoat, suspenders, and a bowtie).
