I agree with the brand blinded statement. Going to go out on a mean spirited ageist limb now and say is often the mums and dads with older teens who still think/want to look 'cool'.
Some of the stuff in superdry is nice, the plainer polos and t-shirts with just a small embroidered logo, but I hate to see heavily logo'd/branded goods on older people anyway. My brother is 32 and wears a lot of superdry and Hollister but its the small embroidered logo (he also wears crew/lacoste/polo etc but all the small chest logo), he also doesn't have children so not copying his teen.
