Sexy Stars: Week of Oct. 25, 2015

It's the week of Halloween -- and while we're sure to see tons of revealing looks on the frightful night, the days preceding the big event proved fruitful for sexy celeb style.

Kate Hudson, 36, was a total showstopper in a soft white suit with nothing underneath. Classic makeup and undone hair completed her sleek, post-Labor Day yet totally fall-friendly, ensemble. Love the look? Try a similar, affordable wide-legged pant and blazer.

Hudson's pal and lifestyle guru Gwyneth Paltrow also rocked a plunging look this week. The GOOP founder, 43, stunned in a black velvet gown reminiscent of John Singer Sargent's famous painting, Portrait of Madame X ... Who wore it best? Try this gorgeous gown with a necklace to recreate the luxe look perfect for the holidays.

It wasn't just about the red carpet, though. Model Gigi Hadid, 20, achieved the seemingly impossible in some killer, head-turning workout gear -- orange and black New Balance Accelerate pants, a Nike sports bra, Adidas Yeezy sneakers and an edgy Saint Laurent bomber jacket (similar style here).
