Inclined toptubes? Can you ride the bike wearing a skirt? -in my case maybe a kilt -though I'm not Scottish.
Handlebar streamers, wicker baskets and turtle bells are out this year...turtle bell maybe's o.k.
Get a studded leather strap for a pantleg wrap (yes, wear pants) and slap a 'Hello Kitty' sticker on your saddle and sit on it. Practice scowling, just think of what the helmet is doing to your hair ..GRRR!
Voila'...tough girl...summer short sleeve weather, a few temporary tattoos.
Nobody will be dis'n your ride then!
