I am 5'4, 120 pounds & ordered a medium based on other reviews saying it ran tight. On me, it ran big, bulky and not flattering. Sadly had to return.
Initially I was so excited about this jacket: it has an attached hood which is great (no need to worry about my hair getting stuck in snaps/zippers).... and best part, it is FAUX DOWN. Many manufacturers do not take animal welfare laws into account (and I can't trust the lax laws in China, where this is made) so I feel much safer going with polyester fiberfill and not feathers, which belong on beautiful ducks.
The lining on the nickel color jacket is a dark violet which, when I tried it on, stained parts of my white t. Why can't they keep it neutral on the inside (grey/silver/black etc.?) The cinched waistline was cut right under my chest, not my natural waist, so I'd have to keep pulling it down to look normal. It is too bunchy in the stomach area & flares out too much in the hips, so I feel heavier than I am, in this jacket. A nice concept jacket, but poorly designed/manufactured. Worth $40, not the $70 they charge.
**If anyway reading knows where I can get a figure-hugging packable faux down hip-length jacket, please comment below!
