Julianne, I was going to PM you since I wasn't sure whether you would see my other reply on the thread, but since you are a brand-new member I think you don't have the private message feature yet on YLF.
I found Boden very true to size - in US clothing I wear a 10, and in Boden (now that they are using US sizes) I am usually a 10, sometimes an 8. If you aren't sure, look at the body measurements in the information for the garment you are interested in. I have found the measurements to be very accurate.
I've never had a problem with quality from Boden - everything I have ordered from there (3 skirts, a dress, walking shorts) has been very well made & held up over time.
I hope that this helps! (What are you interested in ordering? They have so many beautiful items in their catalogue. I could spend a bundle there if I had that much disposable income!)
