Ladies Onesies with Good Length Legs/Sleeves?

[karazeb]

Hi, my niece has asked for a fluffy onesie for Christmas. She is 5'9" and I would like to get her one that will be a good fit on her, but most of the ladies onesies I've looked at have reviews that say they're no good for over 5'6" ish. Can anyone recommend a brand that has good length in the legs and sleeves? Thanks for any.help x

Next usually do a couple with length sizing, haven't looked this year as DDs are all still in good shape but they have been my got in previous years.

I have the same problem and just buy men's.
