Why would a leotard have a hood? As far as I can tell, there is no practical reason for it. It seems to be purely a question of fashion. After Lady Gaga was seen wearing a black leotard with a hood, this type of garment started getting very popular. If you are planning to dress like her for Halloween, one of these leotards would certainly make an easy costume. They are available in several sizes, colors and fabrics.
Wow… how cool are these:
