Admit it: A pair of earrings has called your name. A bracelet has jumped onto your wrist. A necklace has yanked you back into a store. It's like a holdup when it happens: I'll make you pretty and happy! Now just hand over that $500! Easy does it! Fortunately, the acquisition costs of adding to the ol' trousseau have become a whole lot more — what's the word? — comfortable ever since Charm Boutique opened downtown. Kari Kraichely stocks her pretty shop with a stunning array of jewelry created by American designers, including some from St. Louis and Kansas City. The aesthetic is modern, the quality extra-fine. Best of all, pieces come in a range of prices that will neither precipitate a sudden foreclosure on your condo nor propel you to hold up your neighbor while whispering, "Just hand over that $500, easy does it!"
