Professionalize It
You can pair your basic T-shirt with a blazer or a formal outer for a professional look. This way you can just pull it up for a business trip or to a day at the office. However, make sure that your T-shirt is neutral color and not too bright shaded.
Formal doesn’t have to be boring
Pair it with a ripped jean
Pairing your basic plain T-shirt lifts your outfit to a modern chic level. Just grab your basic plain T-shirt and pair it with ripped jeans - black or blue. Finish off with basic sneakers or vans and you’re ready to go. You can even prefer knee-cut jeans over ripped jeans.
Add a necklace
Adding a fancy necklace with basic plain T-shirt does not sound like a good idea until you decide to try it yourself. Definitely not a popular idea to pair them up but it makes your outfit appear extra elegant and so much trendier and cool.
