Another day, another stunning snap from Ariel Winter. The actress took to Instagram over the weekend to share a gorgeous mirror selfie from inside the spa at Miraval Resort in Tucson, Ariz., and she looks better than ever.

In the 'gram, the 18-year-old rocks a super sexy gold one-piece swimsuit by Frankies Bikinis that features a cutout over the stomach with a patterned crochet inset and cute braided straps that tie in the back. The sun shines in the background while her long brunette locks fall around her face in the picture, which she captioned: "☀ready to #relax in the #spa #getaway #sister #trip."

The Modern Family star later shared several more photos from her relaxing weekend getaway, including a sexy 'gram of her and her older sister all dressed up in stylish black ensembles and an image of herself hanging out while wearing a cozy white robe with her hair in a bun.

Happy #nationalsisterday from me and my b;) 👯#miravalresort
