Used to have this modified sj with zipper openings at sleeves' end. Think it's possible to tighten any sj by oneself with a hangman's knot or sth. BUT there is NO GUARANTEE 4 ESCAPE if ur hands can't reach out to loosen the knot or the sth, so DON'T TRY THIS AT HOME by urself!πββοΈ https://t.co/rmNNRt6kNF
