Yes! you should it is better
Only under running shorts, not under swimming trunks. Trust me. :D
No, because there is already a liner to the shorts. Also, most underwear is of a heavier material that would take longer to dry.
regular underwear Think you're wrong on this one. Cycling shorts are meant to be worn commando.
your underwear nothing special
I do not as they will show my underwear line more. I am a girl It all depends on your personal preference.
Yes. If they are sleeping at someone's house, and with their boyfriend or husband they should wear underwear under than pajama pants/shorts. They should always wear underwear under a night shirt/night grown, because it's just like wearing a dress.
For girls, only a bra. No underwear because it will show under you leotard. For boys, underwear thatis it under tights Leo and shorts
To stop pervs from seeing girls underwear and to protect her.
Seems totally unneeded, but whatever floats your boat.
Don't let her wear skirts or make her wear shorts or leggings under skirts otherwise you could buy skorts(skirt with built in shorts) for her.
You do but you where boy-short underwear so it isn't noticeable I know because I have been taking dance for 7 years:)
