Staysfit - it is a real dilemma. From going back and looking at all the photos, my preference is still the Burberry, the cut is beautiful on you and the quality evident. If the Burberry comes in navy, is that a colour that would appeal to you? Navy is a classic colour, whilst a Burberry coat is conservative it is a classic that stands the test of time.
However, for the money of the Tibi or Burberry (even if reduced) it should be love and not less than perfect. Buying an expensive trench should always make you feel just that little bit special each and every time you wear it. I know my 12 year old Burberry still holds that little bit of magic for me and I don't want you to settle for anything less than that especially when looking at paying for an expensive trench.
