SIZING Oopa Baby slings are designed to have a long, flowy "tail." This is the part of the sling that hangs down from the rings, which you pull on to make the sling tighter or looser around your baby. Oopa tails transform a basic baby carrier into something between a fabulous shawl and an entirely innovative fashion accessory. We design them this way in part to add just a hint of glamour to new-mommy life, and in part to be sure there is plenty of fabric to cover Baby's head from the elements, or to provide space for discreet nursing in public. You may also notice that many Oopas carry our signature fabric detail along the bottom portion of the tail. Oopas are intended to be "one-size-fits-most" and measure between 84"-86" in length and 29"-32" in width. We understand however, that "fitting most" may not fit you. Therefore, beginning in January, 2006, Oopa Baby will begin offering a new Petite size, measuring approximately 78" in length. Oopa Petites are designed for women under 5' to approximately 5'4". They may also be the right choice for someone who is particularly slender, or prefers a shorter tail portion on their sling. A petite size can be chosen for any sling we have in stock, by choosing Petite from the size option menu while you shop. The size option menu is available in the detailed product description of each sling, found as you Shop our online store. Please be aware that shipping times may vary for petite sizes, taking anywhere from seven to 10 business days to leave our warehouse. We will contact you immediately if we expect any unusual delay. If you have any questions, please don't hesitate to contact us at info@oopababy.com for help in choosing the size best-suited for you. Additionally, feel free to inquire regarding larger slings, which are always subject to availability.
