    From a long time quilter to sewing my first pair of pants and vest. Excellent directions, pdf pattern was easy to assemble and they turned out beautifully for my grandson. I am buying other patterns and continuing my education in sewing garments.

    Perfect Boys pattern
    Reviewed by (Verified Buyer) on 09/09/2017
    I had been looking for a pattern for pants and a waistcoat for my 2 boys to wear to a wedding and someone recommended this pattern to me. It was my first Oliver+S pattern and it will definitely not be my last! The instructions were clear, the pattern was easy to put together and all the seams matched up beautifully! I couldn't be happier with the finished product - we have had many compliments on their outfits! Thank you for a great pattern!

    I made both the trousers and the vest for a friend's new baby—the trousers in Cone Mills denim and the vest in contrasting quilting cotton. The instructions were really easy to follow and the garments turned out beautifully. The instructions for the welt pockets are particularly great! The paper pattern assembly from the PDF pattern aren't standard, so it took me a little while to figure out how to put the puzzle pieces together. It seems to me that it's supposed to save paper but I'm not sure if it actually does.

    I made this outfit for my 18 month old to wear to a wedding, came out beautifully in grey Essex Linen with a voile lining in the waistcoat and trouser waistband. I use the welt pocket instructions to add to my adult shirt patterns now! Thanks Liesel for making such a cute boys pattern!

    I made matching courdary pants for my grandsons who are 3 and 7 months to wear on Christmas. I was very happy with the outcome! They are adorable! I love how the faux fly and pockets came out. The pattern was easy to follow with directions that were clear and concise. I did not attempt the welt pockets, but will the next time I make them. I look forward to trying some of your other patterns!

    I put together a fun chocolate brown pant and vest set for my 12 year old son (read not easy to find size in patterns) and the fit was perfect. Following Liesl's directions on the welt pockets was so detailed and they came out perfect. The one suggestion I would have is the line up of vest buttons was a wee bit tricky as the front has the slight curve so that took some time to get it quite right.

    Art museum vest
    Reviewed by (Verified Buyer) on 05/20/2016
    My kids gave me a sewing machine for Christmas, the first I've operated in fifty years. I was fortunate to find Oliver and S before I'd wasted much money on other patterns (all still sitting in a box.) I began with the popover sundress and the doll version, and then the lazy day skirt and lds tutu (a big hit with the grandkids.) I just finished the Art Museum Vest today and I am thrilled with it. As with every other Oliver & S pattern I've used, everything is explained, and what I couldn't find on the pattern, I found in your tutorials. I highly recommend these patterns, not only for beginners, but for everyone. Two beginner "duh" moments: 1. If possible, use interfacing that matches the fabric. 2. When pressing the interfacing onto the fabric, also add some to a test piece so that you can test your stitch length and tension before you try to stitch a buttonhole onto your vest. Lots of hours spent pulling out stitches, but on the plus side, I learned to replace my needle. Thank you again.

    I put off making this terrific pattern because I had not constructed welt pockets before. My grandson is now a size 4, so I hurried to make the pants before he outgrew the pattern. I should not have worried. The pants went together beautifully and the instructions were clear and concise on the pockets. I love the outcome and will be making some more soon.

    I haven't got round to making the trousers yet but I have made the waistcoat. The instructions made it very clear and I made a beautiful waistcoat without any issues, I have never made welt pockets before, so this was a first and they turned out perfectly. I used some liquorice allsort sweetie patterned material for my 2 year old grandson he loved it.

    Snappy set for the little gent
    Reviewed by (Verified Buyer) on 08/29/2015
    This is one of my most-sewn O+S patterns (second only to Playtime). I love vests on men and boys alike and this one has great details. The welts go together easily. The pants are also a great choice for church or dressy with their back darts, slanted front and back welt pockets. The pants feature a very generous inseam, which is great for growth. I always turn up a 2"+ hem and then am able to let it down later.

    My only issue with the pattern is that the vest runs very short, as you can see in the pattern photos. I have sewn it five times and have always had to lengthen it at least a full inch. I don't mind doing it, since the pattern overall is excellent.

    I was scared of the welt pockets but between the instructions and the blog post everything went together beautifully. My son loves the vest and doesn't want to take it off! I can't say enough about the beautiful drafting - it's just perfect.

    Great pattern for beginners
    Reviewed by (Verified Buyer) on 06/11/2015
    I bought this pattern to make a little suit for my 2 year old for a wedding using micro herringbone wool tweed.
    I would rate my sewing experience level at 'advanced beginner', but I have never sewn a garment before.
    Both peices turned out really well! I was worried about the welt pockets, but the instructions are very well written and break down the process into clear steps.
    The only error in the pattern I can see is the step where the front pockets are sewn into the pants; I believe the picture shows the pattern piece incorrectly, but the instructions are correct (although I could be mistaken).
    This is an excellent pattern, and I would recommend it highly.

    Take your trouser sewing to a higher level
    Reviewed by on 05/04/2015
    Firstly, I have only sewn the trousers and not the vest. The pattern was easy to follow until I got to the trouser band. I had a little trouble in following which layer did what. Apart from that I was very pleased with how the trousers turned out. I even got complements for them from someone who asked where I had bought them from.

I've skinny sized the Sleepover Pajamas for him a couple of times and he has gotten years out of them. The pattern is fab. My first ever welt pockets and I am delighted with how well they turned out.

    I recently finished this pattern for my boys. The outfits came out amazing. The instructions were easy to follow and the outfits look so professional.

    Art Museum Vest and Trousers Pattern
    Reviewed by on 03/06/2015
    When I bought my first pattern, the Fairy Tale Dress, from Oliver and S a couple of years ago I little imagined I had discovered a versatile source of sewing ideas. I am particular about my creations, about versatility, about so many things too numerous to list here. In short, I have been quite satisfied with the many patterns I have purchased; the Art Museum Vest and Trousers is a perfect example. As I sew for six grandsons and six granddaughters, versatility is important. As soon as I realized the usefulness of the pattern, I purchased it in all sizes.That way I can accomodate my smallest grandson who is 19 months as well as the oldest who is eight and everyone in between. It allows for dressy trousers or pants for play. For dressy pants I simply simply follow the pattern whereas if I sew play pants I leave out detail such as the welt pockets and belt loops. I can adapt the vest for boys or girls. The pants easily adapt to a variety of fabric including courderoy, poplin, broadcloth and others. The elastic waist band allows for my thinner as well as stockier boys; the fit on both is great. Definitely all of these reason and more make this pattern one I use frequently. With so many to sew for I appreciate a pattern I can use in so many ways. It's super to be able to have both a pants pattern I can depend upon as a staple and a vest which brings a a flair and a unique aspect for creative sewing.

    Love the pattern! The instructions are clear and the images are helpful. The pants run long, but that's fine, as they'll just fit a little longer. I added a longer hem on the leg to be able to roll them up in the meantime.

  • Errata

    1. In the first printing of this pattern, there was a minor error on page 4 of the instructions. The second to last sentence of Step 1 under Make the Belt Loops should read, "Cut the two finished belt loops into six 3 1/2" pieces," instead of five pieces.



    Determining Which Printing You Have

    As errata are discovered, they are marked for correction in subsequent printings of the pattern. To determine which printing of an instruction sheet or pattern sheet you have, look at the copyright box which appears on each. Toward the bottom of the box, there is a series of numbers.

    The lowest number you see there indicates which printing you have. For example, if the lowest number in the box on the instruction sheet is "2," you have an instruction sheet from the second printing. Any errors in the instructions mentioned for the first printing have been corrected in your version. If the lowest number in the box on the pattern sheet is "1," you have a copy of the pattern sheet from the first printing.

    Pattern sheets and instructions sheets can be printed separately, so be sure to check the errata notices for pattern pieces against the printing number on the pattern sheet and errata notices for instructions against the printing number on the instruction sheet.
