I'm about 5'5" and normally about 120 lbs so i purchased the small. i'm currently 9 months prego, but i couldn't resist this jacket! i purchased anyway and although it doesn't fit over my belly right now, i'm looking forward to being able to wear it soon! it will be perfect for the chilly office or a casual day. the fabric is beautiful with just the right amount of stretch. like others have said, it has a bit of a navy-ish tint to to it, so it's not truly black. thanks retailer for offering anothe
