okay so boom. I bought this jacket as my 3rd purchase off FN as far as jackets go (I bought a total of 4 with this purchase including this one). The very first jacket I bought , it was a full jacket that was letterman type in a size SMALL because I looked at the reviews & everybody said to size down. That jacket fit like a L on me 😭 so I ordered ANOTHER jacket but this one was cropped so I went off my experience w the first one & ordered it in a XS to which I COULD OF gotten it in a size M for like a comfy / roomy fit yknow? But the XS fit like a true size of a S & was still a good snug fit for me . Oh & for context , I’m 5’7 & a half & weigh 175 on the slim / athletic build side. But yeah , so then I bought THIS in a size M thinking it would be like an oversized fit just like the 1st one but it’s actually a true M. I wish I got a L or maybe even a XL would of matched the look of FN model BUT nonetheless, it FIT so that’s what I’m happy about. So yeah , if you want it to be a fitting like model , go up a size or even 2 🤷🏽‍♀️ otherwise , get your actual size if you want to just wear it as a quick throw on & take off rather than it being part of your FIT . If you know what I mean 😅.
