Hi! I bought this 1982 wedding dress, but it's a smidge tight on me. Definitely wearable but maybe not as flattering as it could be. It has just about 1cm (cm, not inch!) of seam allowance, is there any chance a professional could let it out just a tiny bit (or is my best bet to lose a couple lbs and wear good shapewear)?
