Ipswich swimsuit



In stock

Buy the Ipswich Swimsuit by Cashmerette and soak up the sun! This modern pattern has two cleverly color-blocked variations: a one-piece swimsuit with a contrast waistband or a high-waisted bikini with piping detail. Both suits feature supportive straps, and an optional underwired foam swim bra and boning, so that you’re comfortable lounging by the pool or playing volleyball on your favorite beach. Mix prints and colors for a swimsuit that celebrates your body and your creativity.

What we think: both these variations allow you to colour block your swimsuit and make it your own. Plus you can be confident that the supportive straps and optional underwriting will give you comfort throughout the summer.

Suggested fabric: Swimsuit lycra/spandex, with 4-way stretch (at least 50% in both directions), swimsuit lining with 4-way stretch (at least 50% in both directional), optional contrast swimsuit/spandex for piping (View B).

Sizing: 12 to 28, with cup sizes C – H.

Details: scroll through the images to see pictures of the front and back of the pattern envelope.

    This is my second swimsuit I’ve made for myself having made the closet case patterns Sophie last year. I had high hopes for this as all of Jenny’s other patterns I’ve tried have all fitted me brilliantly with just a bit of basic grading between sizes for my pear shaped, mummy figure. This didn’t disappoint!

    I added 1 inch of height below the waist, as despite only being 5ft 4 I always have problems with swimsuit lengths. This was easy to add to the lengthen/shorten line and everything did end up aligned perfectly. My only 3 points to note
    -the neckline does come up high, I’m not sure if that’s because of the inch I added to the lower torso, but the top of the suit can be seen when I pop a T-shirt over the top.
    -the leg elastic needs to be tighter. The instructions have you use elastic the same size as the leg opening, I wasn’t convinced by this so used the Sophie swimsuit measurements but this still is a bit big, next time I’ll remove an extra inch
    -I used the triple zigzag stitch to topstitch the hem on the curved edge just below the swimsuit back fastening. The stitches popped the first time I wore it. I’m not sure if it’s because my hips are 2 sizes larger than my bust size but just something I noticed that I need to change for next time.

    I swim laps daily and it is a really supportive and comfortable suit, although currently because of the high neckline I wouldn’t want to wear it to sunbathe (although not much danger of that anytime soon!)
