Thanks all!
Ladywone: actually the tailor let it out, not in!
These Burberry trenches are designed for genius tailoring, and I found that interesting, in my geeky over analytical way...
My trench is a size 6. Not petite, just size 6. (for reference, I am 5'0 tall and usually fall into the a 2-4p range). Tailoring involved:
1. Moving the belt (and belt loops) up -- yet there's no hint that the belt was ever attached anywhere but where it sits now.
2. It required NO shortening of the hem at all. I am not sure what that means -- on a person taller than 5'0, would this hit mid-knee? On me, it's right AT knee.
3. Sleeves were shortened a lot. Much discussion about where the cuff should hit. I went with the tailor's recommendation -- leave it on the long side, to where the thumb meets the hand. Tailor mentioned that many customers ask to shorten it to the wrist, and in her opinion, that's all wrong, so she smiled and approved when I chose the longer length.
4. Buttons were moved - OUT, not in. You can't even tell they were moved. They were moved just ever so slightly. I was dubious about this part but I am so glad I trusted the tailor's recommendations. It skims just right, without adding pounds. I actually look slimmer with the buttons moved out. Go figure.
The tailor explained that should I lose weight (I'm carrying an extra 10 pounds right now), she can move the buttons back in. And if I gain weight, there's still lots of room to move the buttons out some more. Either way -- it will fall just right.
And that is the whole magic -- that is why this is a worthwhile investment....
The trick is finding the right Burberry; this one works for me, I think, because the details are such that it works on a petite frame (buttons closer together, belts not overly wide, etc).
