Both skin and clothing applications are effective in their own way. Due to body heat pheromones applied to the skin evaporate very fast putting them into “effect” very quickly. This may be what you want in some cases, but it also means the active ingredients get used up very quickly. In addition, pheromones applied to the skin also get washed away by sweat and broken down by bacteria on the skin. Unscented spray products are easily applied to clothing. Just keep in mind that the “scent” will be on there for a LONG time, and may take several washings to come off completely. You may want to be careful of delicate fabric too.
