Plenty of people can tell you how it feels to their body type, and they can tell you how it looks in their opinion - but really it's just down to you.
Buy stuff, make mistakes, and learn from them.
End of the day, it's Airsoft, it is something we enjoy and it isn't life or death so it really comes down to two things;
A) Does it feel good?
B) Does it look good?
We dress up all fancy and play soldiers so looks is definitely a factor ? Feel cool wearing it.
So plate carrier, chest webbing, battle belt - whatever you like ?
