Here's an article written by a plus size babywearer that goes over all main styles of baby carrier:

If you get a woven (not stretchy) wrap like a neobulle, balibaby, ellaroo, didymos, etc, you can securely tie your baby on in a variety of ways that take a lot less fabric, which is cooler anyway. Not sure how many of these shorter carries work with a stretchy, but maybe someone else has tried it?
Here's my video of a carry that I just discovered and can't wait to use with my newborn. I used 2.7 meters, but I'm petite and it's still really tight. My 3.5 meter wrap works a lot better, and you can size up as needed.
