What is the semantic difference between the two words "undergarment" and "underwear"? I have researched and found out that:
- "Undergarment" is used for any type of clothes which one wears beneath, while "underwear" can be only bra, panties and briefs.
- "Undergarment" is considered a very old-fashioned word these days.
Please have a look on the following links:

Do you confirm my take on this?
