We're doing a lakeside wedding...semi-formal...my girls are wearing these really nice short white dresses with brown cowboy boots...just to give it something different...I have no idea what to put the guys in...we were thinking about incorporating a yellow and having lots of sunflowers...would black white and yelllow be ok together? and then the brown boots...would that clash? what should the guys wear to kinda incorporate both the fun/casual side as well as the formal? no jackets? And if yellow doesn't work...what other pizzazz colors would work? thanks for your help :-)
