Lets be honest the majority of people who are into women, like to see them in lingerie, so it would make sense to gift that to them the view. Also a lot of women feel especially sexy when wearing sexy lingerie.
On the other hand this makes perfect sense to buy together because it is rarely used when alone, can this be a gift though?
P. S: Again not sure about the category. I will put it into shopping and gifts as it is specifically about the situation of gifting. Could also be fashion, or sexuality though.
