tight clothes accentuating your curves

Most Helpful Girl
The guy I had a crush on was not revealing at all but rather the attitude/ personality was very attractive.
Own style of talking, straight posture, etc
Dress neatly, don't wear wrinkly clothes, dress professional and keep a smile on your face.
And of course, good hygiene.
