i KNOW this is a huge issue for many of you ladies!! so, i thought i would share my research.
i have a 2 piece set of leathers... (teknic) that are SUPER. they are ladies venom. teknic makes a FINE-fitting set of leathers for female riders that don't have pink flowers anywhere... no stupid flared legs.... leathers for the female form... that likes to R-I-D-E. suitable for street, track AND the privacy of your own home... when you like to parade around and play "racer-girl-gets-caught-by-bad-ass-racer-boy". alas, i digress.
(i've never played that game, for the record. i just thought it was FUNNY!)
for summer wear/comfort i decided i needed perforated leathers. i did all my research... and got REALLY pissed about how expensive and totally unavailable they were in all the local shops!! i hate ordering ANYTHING. the frustration involved just compounds the disappointment.
i got a one-piece teknic chicane suit from new enough for $299. it's a man's suit size 40. using their measurements i measured myself (with help) and got a size up from my measurements. one does NOT want to be "pinched" into leathers. comfort/movement is critical.
that being said... teknic is predictable in size conversion... and quality. it's not easy finding a suit to fit the subtle, yet significant, differences in the female/male form. i'm about 5'6.5". i weigh about 118. i have a normal girl person below the belt (read birthing-type hips and big kiester) and above the belt i have something that looks like a chicken carcass picked clean of meat. you know... the usual.
the leathers fit really GREAT. considering they were made for a small guy.
there is plenty of room in the chest for the after-market mods. OEM is disappointing.
