... alright, here I found a good close-up of the hotpants and a crochet scheme of the pineapple motif that comes very close and could be used and/or readapted.
... ok, maybe this scheme could be adjusted and used as a basic pattern for the left and right pant legs so then we would have a center seam in the front and back... with some swatching, adjusting and sizing anyone could make their perfect fit crochet beach hotpants... good luck and enjoy! :)
WOW!!!! Here is what I found!!!! You can get Kate's crochet pants on eBay!!!! Just type "crochet shorts" as a search term and you will come right across it!!!! :)
