There is no certain style regarding this. At least not in this age gap. 28 and 29 aren't too much. There is dressing psychology as the way i dress in my 20's i won't necessarily dress the same way in my 30's or furthermore 40's. But these this age gap doesn't count because they are from the same stage.
Primarily people must dress as how they feel satisfied, comfortable and confidential with it.
Dressing also goes to physical appearance. Shape/body type, undertone of skin, eye color, hair color, height, weight etc. . . . if someone wants to wear specifically and sensitively. They must regard such factors when choosing their clothing. Combining them with social events and personal preferences.
