Economize vs Fantasize: Silk military blouse

Fantasize: Elizabeth and James silk-charmeuse blouse: £215

Economize (well sort of...): Whistles silk blouse: £95.00

I saw this Whistles blouse in BT the other day and it instantly reminded me of Elizabeth and James version, which I put on my November wishlist. Whistles alternative is just as luxurious and I would definitely wear it tucked-in with skirts & pants, or with leggings.
