This is a NEW with TAGS Women's Wilson Large Ball Buster Tennis Dress! This striking dress has mesh panels, double straps, a fun triangular cut-out, a built-in shelf bra, and it is UPF +30. This nanoUV, nanoWIK, and nanoBAN royal blue and neon yellow dress is an eye-catcher! My daughter, in these photos, is a size 8 Medium, and you can see that she has extra room in the back. I feel the Large label would best fit a size 10 and possibly a 12. Your fun Wilson tennis dress will be shipped to you quickly as a USPS First Class Package!
