Time for fluff

I'm still waiting on my backordered La Redoute skirt and boots, which have supposedly shipped, but today I received an order I'd placed after that one. All is well except for a brocade mandarin-style jacket which is mysteriously 6 sizes larger than what I thought I'd ordered. I hate doing exchanges, but I don't have any choice with this one. And then there's the red merino wool cardigan. It's marked the correct size, when I try it on it stretches nicely to fit over my shoulders and it zips up fine (although I didn't expect 3/4 rather than long sleeves), but I swear when I hold it up it looks like a medium-size child's sweater. I'm small, but I'm really not that small. Very strange.
