Are you up for bibs + jacket? I couldn't find any insulated coveralls that fit well anywhere I shopped.

For insulated bibs, my Carthartt women's bibs are pretty awesome. Plenty of room for boobs even in the smallest sizes and elastic, contoured waist area. That said, I think I paid about $100 or $120 for mine, but if they are like my unisex Carhartt bibs, they will probably last 20 years with a handful of tape patches. I sized up for plenty of layering abilities under and I'm glad I did. There's plenty of room in the waist, but with the cinched style and most of my sweatshirts not fitted, it kinda bunches up there.

My daughter has women's Berne brand insulated bibs that are similar in style, but seem to have a bit less boob space built in. So if your boobs are huge, you might need to size up. Pockets are different as well. They are significantly cheaper and seem like they will hold up. They didn't have my size in store or I probably would have picked up a pair. Amazon Link

I actually like her Berne coat better than my Carhartt coat. Plan on picking one up at end of season clearance. She has it with her, so I couldn't tell you the style it is or if they have multiple styles.

Not sure how much you want to drop on rain gear, but look into fishing rain gear, especially companies that are geared towards commercial fishing. Grunden and Simms are higher priced but both have some quality product offerings.

I'm optimistic that more companies will start catering to women in the future as more women get in the trades. Right now we're still in that weird period where most companies offer either shit quality for more money because it's pink or it says "for women" or they just sell the same men's styles in smaller sizes. It's a bad deal, because anyone coming out with new styles in smaller production numbers is going to be pushing a price point that isn't ideal, so few will take the risk or invest without knowing how they will hold up or if they will meet expectations, so they will either quit production all together, keep price points out of reach, or they won't invest in future styles/technology. I think it will take several big, household name manufacturers to come out with a quality product, eat the initial starting costs, and advertise the hell out of them to get some actual competition going.
