Psst. You heard it here first, but a tweed jacket is going to become your go-to for Spring - the perfect accompaniment to dresses and cool worn over knits, tees and blouses. We happen to think Deborah Brett has designed a perfect version for Wyse. A wool alpaca blend, with a herringbone weave, this has a boxy fit and bracelet length sleeves (so it feels casual but not too masculine), the one button and single breasted cut makes it extra flattering too.
