Love my red cardigan but it makes me look bulky... any styling tips? 😩

Hey girls, Winter’s here and I’ve fallen in love with this adorable red woollen cardigan. It’s loose-fitted with these cute little bow buttons which I obv bought without a secound thought.. But here a lil issue, the cardigan is adorable solo, but the second I add a thin, fine-knit merino turtleneck the shoulders get snug and—boom—I look wider.Urgh, such a mood killer, I just want to wear it without feeling bulky.

Like...what kind of bottoms would balance it out? Or what could I wear underneath that won’t make my shoulders look huge? Also, any color combos that go well with red without being too much?

Would love some tips from anyone who’s figured out how to make chunky cardigans work for broad shoulders 💕
