There's the rub

Just in case you live in Outer Mongolia or you're Amish or something, here's a recap of what's been happening on my blog the last couple of days:

Me: Please, everyone help me with testing my adult jacket! It's urgent! As soon as possible!
You: We can help! We come in every size and shape, and we can help! Urgently!
Me: *Photoshops herself in pictures*

Now, that's a bit strange behaviour on my part, no? Well, my first excuse is that Jamie is ill and therefore stuck to me like a barnacle. After throwing up almost perfectly formed rice cakes at 2AM last night, a foray through the swine flu helpline this morning, and an appointment with the doctor before which he puked all over the car, he's been diagnosed with a bilateral ear infection. And he'll need to go into hospital tonight if he doesn't stop vomiting...

All of this illness is a perfect excuse in it's own right, but the crux of my inertia is sizing. My original jacket has been tried on by five people: Me, who is exactly my shape. Friend Sarah, who is roughly the same size as me but doesn't have Twiglet arms. Jane, my childminder, who is taller than me and has normal sized boobs. My friend Liz, who now runs half-marathons and is subsequently dinky. My mother-in-law, who is very slim but has wider shoulders than me. Let's get this straight: The coat looks awesome, on every one. But I just can't figure out what size it should be. Until I figure out that size, I can't grade to other sizes. Adult bodies (as opposed to children's bodies) are just so freaking different. And, as adults, we want coats that fit and flatter our bodies. Does anyone have any advice?!
