Showing your pants on the beach is ok but for some reason if you do it on your bike it's completely different.
To retain your modesty you can wear cycling shorts under your dress but as I'm allergic to them (just like I'm allergic to ice cream, Crocs and Uggs) I go for plan b. Plan c if you include riding side saddle.
If you really want to see some pants on a bike, who am I to deny you? Here you go, feast your eyes on this:YOU ARE WELCOME.
