i wear both of them on different occasion, i wear jeans when i go casual parties and day to day basis activities and then i wear slacks for formal occasions such as weddings and christening.
for me it depends on the situation where in i can choose the right one to wear but if i were to choose one of these i think i will choose jeans cause its more fashionable that slacks )
cause i really loved fashion ! so much !
jeans all the time! i'm very active person and i need to wear something that would fit my lifestyle. basically jeans can be matched on almost every kind of clothes. So i go for jeans! i love it!
