Hello Alex,
Thank you for your email! It was great to hear from you.
In Russia, most schools don't require students to wear a uniform. As for me, I prefer wearing casual clothes like jeans and a t-shirt. It’s much more comfortable for studying and hanging out with friends. What about you? Do you enjoy wearing your school uniform?
I’m looking forward to hearing from you soon.
Best wishes,
