Items can vary quite a bit, even within the same brands and sizes listed on their tags. I provide these to save both of us time and money. For the best fit, measure your favorite clothing and compare their measurements to the product you’re buying! Feel free to contact me with any questions you may have and thanks for looking! I try to answer all correspondence the same day but if its not possible I will answer within 24 hours. I ship every day during the week Monday through Friday. If you order something on the weekend please expect it to be shipped on Monday. I ship everything in my store the most economical way I can through the USPS so that I can offer lower prices on my items. If you’d like something shipped in a different manner, please contact me and I’ll do what I can to accommodate your request.
