Whelp i hope you like glorious nippon.
I dunno about 27 but you will find Japanese chinos in size 28.
These ones have a sub 27 inch waist for the size 28 if im doing the math right.
Use From Japan or or other proxy service, should be $5 in proxy fees and about $20 for international shipping.
They also make two looser cuts if you find these too slim
