She bought this suit and it doesn't fit (she's 5'9" 140 lbs - athletic build). https://www.revzilla.com/motorcycle/dainese-womens-racing-leather-race-suit. It's been down but looks like a super low speed tip over - just cosmetic scuffs - she bought it that way. SZ 42 - (she bought a two piece A stars size 44 that fits her perfectly for sizing reference). 450.00 shipped A stars Stella Jacket size 42 (brother's wife - she's 5'1 don't know her weight but athletic build). Worn once: 120.00 shipped.
What about the suit didn't fit your wife? Too short for her or too tight? My gf is 5'" and probably 130 - athletic, big arms, fairly wide back. Think it'll work? If you still have it, that is.
