Do you think it's bad for a teenager to buy expensive and luxury brands like Gucci?

Not at all! I'm 17 too and i spend a lot of money on designer clothes/bags and to be honest i have a job and i've earned some of my money so its not just me being spoilt or a snob though people often call me those things... i think a lot of the time people are simply jealous, do what you want and wear what you want its the 21st century and a little luxury isnt bad, especially if you earn your money
