Free Crochet Pattern: Lock It Down Dress

Free Crochet Pattern: Lock It Down Dress

There are affiliate links for Amazon and Yarn Crafts & Coffee included in the post below. If you click on them and make a purchase I will receive a small commission at no extra cost to you. Thank you for your support :)

Below you will find the free crochet pattern for the Lock It Down Dress!

Hi, its me, Emily at Crochet Aweigh! The “I Think He Knows” collection is back for a couple (?) more patterns in November! I Think He Knows is a song from Taylor Swift’s Lover album and it is SO catchy! It is a cute song about having a crush. There is a part of the song that goes, “I think he knows he better lock it down or I won’t stick around ’cause good ones never wait”. If I was trying to “lock someone down” I would wear a fun and flirty dress! The Lock it Down Dress is just that with its strapless design and ruffles!

If you would like to support my very lofty yarn dreams then you can purchase a PDF of this pattern from my site, Etsy, or Ravelry.

Pattern Notes:

  • This dress pattern is considered intermediate level.
  • This pattern is written made to measure, so as long as you have the measurements for yourself or whoever you want to make this top for, you can make it to fit.
  • This dress is designed to fit snug with 0″ ease.
  • The dress is based on your bust measurement.
  • For reference, my bust is 42.5″ around, so that is what the sample is based on. I wear an XL or size US 14.
  • The concept is to increase or decrease the number of double crochets per shell based on your body. Below I include instructions for how I made mine fit to me, but you are welcome to increase or decrease as you see fit.
  • Lion Brand Summer Nights is discontinued, but you can use any fingering weight cotton or polyester yarn!
  • Pattern is worked in the round without turning after each row.
  • I didn’t do a regular wet block on this, but I did wet down the edges of the ruffles and hung it to dry. The ruffles were rolling up a little for me.

Materials:

  • Lion Brand Summer Nights – Fingering #1 weight. This yarn is hard to find, but you can also use Copper Corgi Savannah Sock Glitzy for a higher end option!
  • Sample used 550 grams or approximately 1975 yards, 2.25 skeins of the Summer Nights
  • US size F/3.75mm crochet hook
  • Round Elastic Cord
  • Soft Tape Measure
  • Tapestry needle
  • Scissors
  • The Lock It Down Dress Pattern: either free on this page, or paid on my website, Etsy, or Ravelry.

  • Ch – Chain
  • Fsc – Foundation Single Crochet
  • Dc – Double Crochet
  • Sl st – Slip Stitch
  • St(s) – Stitch(es)

  • Shell – a certain number of double crochets into one stitch
  • RS – Right Side
