I'm 5, <100 lbs. and I just got the jumbo, lamb, GHW. Both DH and SA said it looks great on me. Personally, i think it depends on how confident you are on wearing big bags and how it makes you feel. If you're not used to seeing big bags on yourself, you'll feel awkward and that shows. I suggest wearing silhouettes that elongate frame when you try jumbo in store.
