Crochet Pattern | Flirty Frills Pullover

Introducing the Flirty Frills Pullover. This sweater is a sweet + feminine little sweater featuring an adorable decorative surface ruffle. I've used one of my very favorite yarns from WeCrochet called Andean Treasure. This 100% baby alpaca yarn really elevates the look of almost any knitwear project, and truly makes this sweater extra luxurious.

The Design

This sweater is labeled as an intermediate level sweater (mostly due to the ruffle technique). It's helpful to have made a garment before, but not absolutely necessary in order to attempt or tackle this project. It is worked from the bottom up, creating two square panels (a front and back), seaming them together, adding a perpendicular ribbing to the neckline and bottom hem, attaching sleeves and cuffs, and finally, adding the optional surface ruffle.

The surface ruffle is a general technique. The pattern links to a video that shows you the overall technique/formula for how to add the ruffle to your liking, but does NOT include specific pattern instructions on exactly where and how to apply the ruffle for all the ruffle options/styles. The ruffle is a personal touch and should be customized to your body and fit preference on the sweater. Please be aware of this when purchasing this pattern. There are a number of creative + exciting ways you can apply this technique! Have fun with it!

Fit + Sizing

The Flirty Frills Pullover has a roomy, boxy fit, drop shoulders, crew neck, mid-length, and long sleeves. Sizing is based on Craft Yarn Council's standards.

It is designed to have a positive ease of 8-10". To select your size, measure your bust and find the garment circumference in the chart that matches approximately 8-10" larger. If you prefer to have more or less ease, select the garment circumference that reflects that number in inches compared to your measured bust in inches.

Yarn Substitutions:

Andean Treasure is labeled as a category 2 sport weight yarn, but in my humble opinion, it is much closer to a category 3 DK weight yarn for this project. If planning to substitute a yarn, please keep this in mind. I highly recommend making sure you make a gauge swatch. Small differences in gauge can lead to big differences in project outcome. For more on gauge, you can read this blog.

  • WeCrochet CotLin DK | If you're looking for a light, cotton yarn for this project, this would be a great choice. It is a tanguis cotton and linen blend that is quite durable, is easy care, and softens well with wash and wear. It also comes in lots of beautiful colors. Just keep in mind this yarn is a slight bit more narrow than the one I used.

  • WeCrochet Brava (sport) | This is an economy acrylic yarn that is actually quite soft and drape-y (especially after steaming or blocking/washing). It's easy to care for and comes in a lot of colors, including a fair number of dusty shades and earthy colors. If you're looking for an economy yarn substitute, I would probably recommend this one.

  • Lion Brand Coboo DK | This cotton bamboo blend is a really drape-y, cool-on-the-skin yarn, that makes a great, really wearable and comfy sweater.

  • We Are Knitters The Cotton | I have never personally worked with this cotton yarn, but I hear that it's a dream. It is a 100% Pima cotton from Peru that is labeled a sport/DK weight. From a cotton standpoint, it's really luxurious, the color selections are gorgeous, and there's even a speckled variety that would be fun to try.
