DIY: Sweatshirt Blazer

*EDITED 2/9/11 with reader suggestions!*

So, I made this sweatshirt (slash cardigan slash blazer?) kind of on a whim. Didn't plan it up, improvised and made it up as I went along. Let's hope it makes sense. By all means, if you decide to make this - improvise the heck out of it and see what works best for you !

ALSO - save two of the scraps leftover from this project. I'll indicate what pieces to save. DIY's using those leftovers coming soon ;)


- Crewneck sweatshirt. Hanes is about $5. *
- A good pair of scissors
- Measuring tape
- Hot glue gun...BUT preferably thread/sewing needles
- Vintage brooch (possibly)

*I used a size Medium. I think, because of the nature of the finished product, a small would have worked better for me. For reference - I'm pretty small, about 5'2", and usually wear a size small or medium (but usually a medium for comfort's sake). Given that information, you can hopefully gauge what size sweater you can work with. Just remember that these crewnecks are not fitted to begin with.

1) Measure the exact halfway point across your sweater.

Use some pins if you'd like; you'll be cutting straight down the middle.

2) Choose a point several inches from the bottom; this is where the diagonal fall of the top will start. I measured about 8 inches up from the bottom and pinned these points.

3) Cut off the bottom, right above the seam. (Save the bottom piece!)

4) Place pins in a diagonal line from the point you measured earlier to the bottom left and right corners of the sweater.

5) Cut along the pins. ONLY the FRONT/TOP layer.

6) Going back to the vertical slit you made in the middle of the sweater - accordian fold both sides so that there about 3 or 4 folds. Pin this and carefully try it on. You will most likely have to readjust the folds for a better fit, several times.

For me - I made 3 folds, tried it on, sewed the folds down, tried it on again, then made a deeper/diagonal 4th fold to give it some shape. Then sewed this fold down.

EDIT: I'd really recommend using a needle and thread to secure everything together; it will hold up much better than hot glue. I used hot glue the first time around since I was just playing around with the idea of making a sweatshirt into a blazer, but a needle and thread would be a much better choice!

Figuring out the folds be a little tricky, as can trying to get the sweater to have a fitted - well - fit to it. Just keep trying it on and re-pinning until you get it right.

8) Cut off the collar right along the seam. (Save this, too!!)

9) Line some pins in a diagonal line on the upper most part of the collar. Repeat on the other side.

10) Cut along the pins...

11) Aaaand you're all done. I used a brooch as a closure, but this can be a little tricky since there's so many layers of fabric. I'm sure you can figure out something, though!

*Check the comments for some great closure suggestions by Aureolis!

For a DIY that I didn't actually plan out, I think it turned out okay. If you decide to make this, feel free to share some tips, tricks or suggestions.

Check back soon for two mini DIY's with the leftovers!

  1. aahhhh this is so fierce. So cute on you too! using the heart pins are an added bonus :)

  2. this is so cute! i love blazers but i have never done a DIY project before. i wanna try this but im scared, lol.

  3. LOVE this! I'm totally obsessed with revamping plain sweatshirts. I am absolutely gonna have to do this!! Love your ideas K, you are so creative! Keep it up! xxooxoxo Lia

  4. Brilliant idea, and these pins are to die for...
    Another option for closing the blazer could be:
    -cut a small hole thru all your folded layers on each side of the blazer
    -then connect the both sides with a wide satin ribbon and colse the blazer with a big boe in the front.
    -guess it would work also pretty well if you hot glue a piece of rippon between the layers at each side or even fix it with needle and thread

  5. Oh geesh, here's another thing for me to add to my list! I went to Michael's yesterday and carried around printed out pages from several of your projects in search of everything I needed! Looks like I have to head back once I have money again! :p

  6. This is such a lovely reconstruction to a boring old Hanes sweatshirt!
    (I'd recommend never using hot glue on clothing projects, though - as it usually won't stay stuck over time, and it renders the garment completely unwashable. Use fabric glue [if you must use glue] instead - or fusible double-sided interfacing or hem tape! Though as you noted above, hand-stitching the folds is probably the best option and most durable...:-) I'll be linking in my next Monday's DIY Links of the Week! Fabulous job!!:-D


  7. Man oh man, I'm so happy that you commented on my blog. Your tutorials are wonderful! Great stuff, I'm now a new faithful follower.

  8. Holy snaz that is cool! And it looks so soft yet chich! :D

  9. Your instructional photos are great!

  10. Thats really lovely n cute
    looooooooooooooove d idea of sweatshirt blazer

  11. tripping over myself with this post. Just found your blog, followed already. its past midnight and I dont think I'll be getting any sleep tonight.

  12. yet again... another fantastic idea! I love it!

  13. oh my!!!! Ii got to try this...I am actually rummaging over my closet to see what clothes can I use for more DIY eheheheh


  14. very cute!! hmm but do you think it'd look fine if i left the bottom of it and didnt make the triangle?

  15. Lovely idea, I shared it on my blog as a DIY idea! I am still learning how to sew, so I might try this one out! Maybe putting a lining around the collars would be nice (but tricky?) anyway, it's a cute idea, I see very nice embellished blazers for sale in hip colors, but they are so expensive.

    Buying a sweatshirt in a fab color (what about bright pink?) and make it into a blazer like you did is a lot cheaper and more original!

    Thank you so much for the idea, I became a follower of your blog, I am curious what you come up with next!

    Hugs, Nienke

  16. where did you buy the hanes sweatshirt? i want to make this so badly! i went to 2 diff. targets and i cant find them :(

    1. walmart has them and kmart does too for 4-5 dollars each


  18. I am extremely impressed with your writing skills and also with the layout on your blog. Is this a paid theme or did you customize it yourself? Either way keep up the nice quality writing, it's rare to see a nice blog like this one these days..

  19. I think I'm going to try this with some bias tape on the lapel like the stuff Ralph Lauren is throwing around these days ( iron down the faux lapel so it looks like I actually spent money on it. This is a pretty nifty little project, kudos :D

  20. This is an awesome idea and a much better step by step than some other "revamp the sweatshirt" ideas ive seen on Pinterest. Another closure idea: stitch some cording in a small loop on one side and sew a funky button on the other side. Loop the cording around the button to close. Thanks for the new idea, cant wait to try it!!!

  22. Excellent whim project! I love when they turn out great like yours did.
    And I thought of a modification for mine. I used washable markers instead of pins to mark cutting lines.
    Instead of cutting straight down the center, I cut an upside down Y so I would have a big triangle that I could sew onto the waist at the back to make a high-low "hemline".

  23. Now I have to go get some sweatshirts to play with. The tute is awesome.
