Probably. And, I did. I mean, when it's -10 degrees out in December, you tuck your shirt because it's f-ing cold. I'm not that slender anymore (not fat, either) and certainly not 15, and tuck in for work, for musical performances, all sort of things. But, if the temperature is favorable and comfort is really the only concern, then there's no tuck. I hate having my shirt and movement hemmed in with a tuck. It's difficult to get it to not be constraining and actually comfortable.Man, with that kind of slender body, you could really get the most out of a good tuck.
