Theory women’s navy suit

Navy women’s suit. Pants are a low rise, straight leg. Suit was altered from original sizing. Jacket tag is an 8 and pants are a 4. I would say both fit like a women’s size 2. I’m a true 4 on top and 2 for bottoms and both are a bit snug. Inseam 30.5” Waist laying flat 15.5” Armpit to armpit laying flat 17.5”
