I don't know what to buy for my shop i need a style to focus on

People worry to much about the value of colours in TC. Pick a colour you think looks sexy. I really like Void (happens to be expensive), Copper and Amber.

If you like Orc buy it. If not save a little TC and get something else. What is your favourite colour?

orc is a good color for new people because it's so incredibly cheap. it's usually looked down on but I have focus on orc in my set and I love it. ;3

i only picked it because its cheap and i can put in my shop

If you're looking to buy and sell, then starting cheap is a step in the right direction. There is normally a demand for Orc as it's the first colour bought.

i like orc, and it's awesome, so don't put words in my mouth...

i have almost all orc things what else should i work on?

Get all things so you can earn Full Orc Achievement

But for my shop what should i do?

orc isn't a bad idea for a theme. go for it.
