@Mizmazzle It is roomy in the waist, to where I can probably pull out the front about 1.5 inches. I went with 31 waist assuming that a 29 or a 30 would be too small after a wash. That might be the mistake. I do think a 29 would be really snug and tough to fasten, but would have stretched. 30 might be the happy spot.
With the 634 in a 30 waist I could barely button up without sucking and some serious pressure in the sensitive bits. That also lead me to a 31, but I think the 634 and the 888 top block are entirely different. The 888 is baggy around the glutes and crotch whereas the 634 is nearly skin tight.
I hope that the 555 is the happy medium for fit and sizing. I am going for a slimmer look, but don’t want to be so restricted in my movement that I can’t crouch down, climb stairs or sit comfortably.
Alas, we live and learn. FOR SALE!! Thanks for the input.
