5. Personal preferences:

Ultimately, the decision of whether or not to iron your underwear and socks comes down to personal preference and the level of care you want to give to your garments. Some may prefer to look impeccable at all times, while others may consider ironing an unnecessary chore.

In summary, ironing your underwear and socks is not strictly necessary from a hygienic point of view, but can help improve the appearance and durability of these items. However, this is a personal preference and there is no hard and fast rule to follow. Do what works best for you when it comes to ironing and focus on the aspects of laundry care that are really important to you.
