I test rode a Terry Classic in the 17.5" size in 2002 before I ordered a Terry Isis. There is no 17" size, or at least there wasn't in 2002 or 2003 when I did this. The sizing went 16", 17.5", 19", 21", 23".
I am 5'2"-ish with around a 28.5" cycling inseam, and the 17.5" fit me perfectly. I suspect it would be too small for you as GLC says. Sounds like you'd probably need a 19".
Sorry to disappoint, but better than buying a bike and being disappointed!
