I received my 0305 a week ago. As stated on the website, sizing up by to sizes from my usual size (31 in 3sixteen) got me a perfect fit.
This is by far far the best fit I found in a momo jeans! ( I tried 705, 400, 702 and own a 1705 in 32). The cut is very slim and tapers a lot.
The 18oz softened quite fast after 2 days but the denim is still very rigid.
I ordered mine in indigo/grey and with the slim cut and the dark colour they look quite stylish and can be dressed up...
