I would give a moby wrap a try for the first few months. I'm a size 16/18 (but more like an 18 right after we had our daughter and were using the moby). I'm also tall with a long torso. I found the moby fit perfectly fine. They are really only for babies up to about 6 months because after that you'll want something more supportive, like a woven wrap, but they're more affordable than most woven wraps, so a great thing to try at first to see how you get on with it. Some people find they only really babywear for the first few months anyway, or some people, like me, still wear their nearly 3 year olds, so it's something to try and if you get on with it you can invest in something else later. You can also find secondhand ones as well. Beyond that, if you do want something more suitable for an older baby or a toddler, a size 6 woven wrap would definitely do the trick, I would assume. I had a size 4, which didn't leave much extra length. I could pretty much just get it tied without more than a few inches left over, but that worked perfectly well for me. A size 5 would probably also work, but I'm sure a size 6 definitely would. We also have an Ergo carrier and I can just about get it buckled, so you might want something with a longer waist strap or the extender, but that's an expensive investment, so I could get to a sling meet and hire one before you buy (some will even do hires by mail if it's too far).
