I hate all branding on clothing. Less is better. It's hard to avoid sometimes, though. Nike and Adidas are best for trainers and football boots, but I wouldn't casually wear their T-shirts...
I don't want to have to constantly buy the 'latest fashion' trends. I like plain and simple... good quality that will last.
Day to day at home, I usually wear some some £5 t-shirts from Next bought 5 years ago. They still look and feel good.
For the weekend, I occasionally like to treat myself and buy Reiss and Sunspel clothing. Good quality, no branding, but expensive, so I only buy when on offer.
