Flower Lace Semi-Sheer Bra with White Lacey Thong Bra and Panty Set by Donna Di Capri. The lingerie, dresses, swimwear, and sexy costumes we offer are all form fitting and tend to run small compared to standard dress, pant, and letter sizing. It is important to know your measurements to find the best fit. To find the most accurate sizing you must use your bust, waist, and hips measurements. If you need to know what to measure to get your appropriate measurements use the diagram to the right. If you are between sizes it is always better to go larger. You can always take it in. Please keep in mind your bust measurement is not your bra size. It is the measurement of the fullest part of your chest. If you use your bra size it will be too small. One Size Fits Most items are suggested to fit 90lbs - 140lbs. One Size Fits Most Plus or Queen items are suggested to fit 160lb - 225lbs.
