I have a Bonobos sportcoat and the bottom part of the lapels aren't necessarily sitting "flat". It is almost like they need pressed so that they will lay flat vs. sticking out. From the side view when wearing the jacket it makes me look heavier than I am. I would post a pic but unsure how to do so. Anyone have a solution?
Do the lapels lay flat when the jacket is on the hanger? If not there is a structural issue with the jacket and you should try to return it. If the lapels puff out only when you wear the jacket there is a fit issue. There are a number of issues that can cause this to happen, your best bet is to take it to a reputable tailor and have them look at it. Unless the jacket is sized incorrectly or cut in way that is drastically incompatible with your body it should be a pretty quick and affordable fix.
That is a different issue then I thought you were describing in your OP so please disregard my first post. Just looking at that picture if you had not told me there was an issue with the jacket I would have never noticed a problem. Is it a new jacket? If it is I would return or exchange it immediately, if not I would take it to a tailor and have them look at it. They should very quickly be able to tell you if there is a structural issue causing the jacket not to drape correctly, or if it just needs to be pressed.
Maybe it fits as it should then. Here is a front shot, you can't tell from this angle, but just wanted to share Anyways, lighting is poor ...maybe it's not so much lapel sticking out but from the bottom of the lapel to the bottom part of the jacket..is that all lapel roll?
