First one looks like an Aikido uniform. Agree with the other posters that the second one looks slutty. I like the third one except for the checked pants. Have you considered a solid gray pants? If you want something that is Asian but more modern and classy how about something like the Cathay Pacific Flight Attendant's uniform.
Yea If i do the last one it will def. be solid pants black or grey or brown. And yes I will get pics of hostess with the final uniform just need to get a final uniform. Thanks everyone that has helped any other suggestions are welcome
