Absolutely cute button down cardigan

Ever so cute! Wear over a dress or skirt. Great for a day at the office or drinks after work. Gives me great balls of fire vibes somewhat. Tag says one size but I find it is very oversized. No fabric content tag on the inside so not sure what material it is. If it were my size I would keep it. I feel like the buttons aren’t lined up properly and you don’t want to stretch the fabric too much otherwise it will have a gap.
