Traveling to Chandigarh (New Delhi)

Hi all, i will be visiting Delhi in April and was wondering if anyone can
suggest a safe and convenient way to travel from Delhi to Chandigarh.
Also any tips on where to shop for some good suits in Delhi and Chandigarh.
Also using this opportunity to meet up with anyone who is a Professional Coach. My company is a coaching and consulting company and we are always looking for coaches.

Cheers
