Hello everybody! I'm new here. I just want to ask for help or suggestions on how I should wear my newly bought plaid shirt. I've worn short sleeves with designs similar to this one but this is my first time wearing a long-sleeves. I dont have any idea on how I should wear it. (tucked in/not? sleeves rolled/not? what to wear as undershirt? buttoned/not?) Mom told me to wear this one as undershirt but well, i dont know. Should I go for this one or just wear a plain white shirt? or perhaps a black printed shirt? any suggestions please? I'm planning to wear these for my upcoming christmas party. Just wanna sport a casual look so...any thoughts guys? Thank you so much! P.S. I'm 5 foot 9 inches, medium-built body. Maybe this might help with your suggestions.
