The bag does look great on you! If you plan on using the Birkin for everyday and don't carry a ton...based on your size I would seriously consider a 30 over the 35. If your bag is a 28 it looks great on you and the 30 would be a bit bigger. I would only go for the 35 if you need more carrying space. 30 would be fine for size/wise on your body frame. My opinion
