The product line was developed for model adults in mind as our candy. With this said, we have modified the design to 1 location for youth T shirts. Adults came first for basketball camp fund-raising & so youth understand the privilege it is to own a custom garment and take the style and basketball camps seriously. Youth T shirts are 4.5 oz. cotton or cotton-blend at least up to 5.3-6.5 oz. It just depends on the season/region. Always order sizes that they normally wear/buy. All Money Enterprises $ garments come with custom tags. Tons of colors for them so just pick your favorites. T shirts are a universal size and normal shape for both boys and girls. I found XXSmall Ts for 1&2 year olds too, ladies! Not every color is offered in XXSmall so shop careful. Any color not available in XXSmall is clearly labled "no XXS". Product note: Vinyl heat transfer option is similar to screen-printing with the same great aesthetic and durability just a slightly different process.
