4 Ways Technology Can Help You Figure Out Your Actual Size

Real Simple staffer Brandi Broxson put the latest find-your-fit services to the test. Here's her firsthand account of how they measured up.

How It Works: Upload two photos of yourself—front and profile—wearing a tank top and a bra that you usually wear. ThirdLove’s iOS app will determine your optimum bra style, band size, and cup size.

How It Worked: I was skeptical that my size could be configured with just a couple of photos. But I was amazed when ThirdLove’s recommended 24/7 Classic T-shirt bra fit perfectly—and in a band size smaller than what I normally wear.

How It Works: You’ll find the True Fit clothing-size finder on many major retailers’ sites (Nordstrom, Macy’s, Ann Taylor). It uses your height, weight, and body shape to give you a personalized size and fit rating (excellent fit, good fit, not recommended) for most types of garments.

How It Worked: A shift dress that was classified as an “excellent fit” was a bit too snug around the hips, but ankle pants with the same rating fit well and were the right length, a common challenge for a tall girl like me.

How It Works: The site determines your “Fitcode” number by taking into consideration your jean size and hip, thigh, and bottom shapes—no measurements needed. Then it presents you with denim options that will best fit your body and a video of an actual person with your Fitcode trying on each pair. Once you’ve made your pick, Fitcode provides a link to purchase the jeans on a retailer’s website.

How It Worked: The pair Fitcode recommended suited my curves and didn’t gap at the waist (a usual problem). Next time I’ll order a longer inseam, though.

How It Works: Thanks to a robust customer-review community, the site and the app allow you to see what other women with similar measurements look like in the site’s rentable designer dresses. Even better, you can have an extra size sent to you at no charge.

How It Worked: Women of my same size and height gave rave reviews for a peplum shift, and for good reason: It flattered my hourglass shape and wasn’t too short.
