Size L Patterned T shirt style dress

Purchased this from The Mint Julep Boutique however I have not worn it because it is too small for me with the lining on the inside. For reference I am a size 14 with a larger chest. Would work for a size 8/10 I would say and I'm pretty sure that's what the website recommended but I loved the pattern so had to try! Really even more beautiful in person and perfect for the summer months and traveling abroad!
