That's the problem, I'd like to try on the different sizes but unfortunately they only have a size medium. I can get an oxford under there but it's pretty tight. If it stretches out then that would be great. I guess my question is hard to answer since everyone likes their cardis to fit differently, but I appreciate all the input so far. I did manage to get measurements for the M and L although I'm not sure how accurate they are, but just in case anyone needs them as a guideline: size: M L pit to pit: 47 cm 50 cm shoulder to shoulder: 45 cm 47 cm arm: 64 cm 67 cm collar to hem: 62 cm 65 cm So, stick with the M and I get a tight fit in the chest, shoulders and arms but perfect length. Go with the L and the body and sleeves become too long but the chest/shoulders fit comfortably... If it's not too much trouble, can you guys post fit pics? Superbobo? tooshay?
