I'll be honest, I haven't found my perfect fit in Dovetail sizing. I went through multiple exchanges with the Freshleys overalls, and ended up settling for a size 12, because 10(my usual size in other brands) was too small, and I was swimming in a size 14.
The problem I've found with the Freshley and with the Day Construct is that while these garments are supposed to be tailored to the curves and shapes of a woman's body, the thighs are way too tight and the waist gaps so badly, I'm constantly pulling up and adjusting the seat and rise of the pants. I really wanted to love my Freshleys and my Day Construct pants, but I think I'm done trying to find the best size in Dovetail garments. I'm glad so many folks have had a great experience, I'm just not one of them.
