Hello!

As some of you know, I am looking for a winter coat, specifically a pea coat that I will be able to be worn in fairly cold weather.

JenW found me this one at Land's End:

What size should I order?

My measurements are
chest: 45.5"
hip: 54"

In the 18W, the "garment" chest measurement is 51"
The sweep, (ie the bottom of the coat) is 56 1/2"

Will this be enough room to wear a cardigan underneath? (I will not be wearing a blazer). Is 2 1/2" at my hips enough room for the jaunty swing of a peacoat or will it look silly once I have a pair of jeans on underneath? I have no clue.

The 20W measurements are as follows:
Chest: 53"
Sweep: 581/2"

I have no idea what any of this actually means.

Oh and compounding the problem: I measured my arms as LE suggests: from the middle of the back of my neck, arm crooked, to my wrist--and my arm length is 30"

the armlength for the 18W is 34 3/4"
How difficult would it be to take up this sleeve?

Thank you all so, so much.
