Either you're getting smaller Katie, or your clothes are too big for you

During an outing in New York on Thursday the usually sleek actress stepped out in a see-through vest and low-slung  jeans, which swamped her petite figure. Her new look was more in keeping with that of a stay-at-home mum than the multi-millionaire wife of Tom Cruise.

But Katie obviously liked her new look, wearing the same rolled-up jeans with a clean white t-shirt and oversized navy jacket yesterday.

The casual style was reflected by her footwear, with the slim-line mother at ease in sandals and ballet pumps, rather than her usual sky-high heels.

Her wash and go hair had clearly received very little attention and her huge sunglasses covered most of her make-up free face.

The star was attending a rehearsal session for her upcoming Broadway show, All My Sons, which opens in October.
