I certainly hope not... 'cause I'm older than you... 35 and I love my soufflot. I carry her all the time.
It's really about what you like, not what other people think. Do you love the bag? then carry it!!
What is it that makes you think it's "too Young?"
I carry mine a lot... and I wear it with everything from jeans to work clothes, in fact today I am at work, wearing black linen wide leg pants, a black sleeveless top (it's 85 outside today!) bright red shoes, my red soufflot, and pearls.
Like I said, wear what you love... there's no such thing as "too old" for anything LV.
