What's a bag you would recommend for an Asian guy in his early 20s? Prefer something not as flashy but is obviously designer. Wouldn't wear a bag that's not brown or black also. Either crossbody or shoulder is fine, no belt bags. Maximum budget is 3-4K but the lower the better. Just need to carry my phone, airpods, a wallet, power bank, and maybe some beauty items (chapstick, travel cologne).
