Sizing
At Vitamin+J, we offer both made-to-order pieces and one off ready-to-ship items.
Our made-to-order designs can still be customized, so you get the best of both worlds, please contact us if a size isn't available and we can work on something together. To find your ideal size, check out our sizing guide or reach out for custom adjustments. While made-to-order items may take a bit more time, the result is a piece that’s tailored specifically for you.
Please note sizes may vary slightly from design to design, if you are unsure please feel free to send me an email <3
