I really liked them to go under Kayleigh's skirts, but they are a rather bulky wrap. We wouldn't tend to use them with jeans. Actually a lot seem to go for sale second hand without much use, so you can pick yourself up a bargin. We were initially going to get a large thinking Kayleigh could grow into it if was too big, then we got a med. as a present and were very glad it was a med.
