I will get in touch with Shawn and see if there is extra expense for alterations. It seems that what my son said is right. "for us, we gotta go bespoke or not go at all".That’s Shawn’s trucker pattern
While it’s slim fit it is also straight torso
I nipped a few inches off the waist in custom measurements to get some taper.
Which I think with your shape you also need more taper.
You can send it back for alteration if shipping cost works out. Better to have a well fitted jacket you would wear than one that just collect dust in the closet.
The gasoline smell description is bang on. Petroleum by product aka paint (I think) off gas. A week out in the sun will do. More if cloudy. Shawn really need to hang these out before shipping them. I’ve read somewhere another jacket manufacturer set his out on the roof to tan before shipping to the customers. It’s not chemical, it’s the same smell as new synthetic yoga pants. The more elastane the stronger the smell.
