EASY SQUARE NECKLINE SUMMER TOPS: 10 Indie Sewing Patterns You Can Sew and Wear in a Weekend

Looking for the perfect square neckline top pattern for summer? You're in the right place. Square necklines are one of the most flattering and versatile styles to sew — simple enough for beginners, yet stylish enough to wear on repeat all season. They're the unsung hero of summer sewing — easy to fit, easy to sew, and somehow always look 10x more put-together than they actually are.

I've spent hours digging through our pattern archive to round up 10 of my favourite square neckline tops — all beginner-friendly, all sewable in a weekend (or less), and all destined to become summer staples in your handmade wardrobe. From minimalist tanks to puff-sleeve stunners, there are easy sewing patterns to sew and style. Let's dive in!

Madswick Camille Chemise

Camille is a modernised chemise-style dress or blouse with a wide square neckline, puff sleeves, and special details like box pleats and gathers around the bust, underarm, and sleeves. It doesn't have any closures like buttons or zips, so it is easy to pull on and off.

Sizing: 0 – 15 (approx. UK 4/6 – 34)

Sewing Therapy Rectangle Top

While simple rectangles are the building blocks of this pattern, once constructed, the results are anything but simple. The designer has put together three views, but you can mix and match all the elements to create your own version! This bestseller is a good buy.

Sizing: XS – 3XL (approx. UK 6 – 24/26)

Les Perlines Dayscape Top

The Dayscape Top is a flirty spin on the boho blouse, with a signature Les Perlines twist! It features a playful tie detail at the back and adjustable front drawstrings that let you control the gathers for a fit that works on every body.

Sizing: AA – O (approx. UK 6/8 – 30/32)

Friday Pattern Company Collins Dress and Top

This quick and easy sew comes with a few options to play with, and has handy hidden features. Sew it up as a top, short dress, or tea length dress with a choice of two cup size options (B/C and C/D) to achieve a great fit.

The back has low or high (bra-friendly) options, and most importantly, Collins has an integrated shelf bra. It is form-fitting without being too tight, and the hemline features a slight A-line sweep, balancing the proportions out beautifully!

Sizing: XS – 7X with B/C and C/D cups (approx. UK 6 – 34)

Oh Me Oh My Nova Dress and Top

This square-necked beauty is the perfect opportunity to try your hand at shirring if you haven't done so already. Nova features a shirred bodice with an optional small or large ruffle. There are four puff sleeve options and three length options to choose from, which should keep you busy. The pattern includes detailed instructions to make shirring a breeze!

Sizing: XS – 4X (approx. UK 8 – 30/32)

Tessuti Fabrics Romy Top and Dress

Not tempted by the options so far due to your minimalist leanings? This could be your match.  This simple hip-length top or midi-length dress is an easy addition to your summer wardrobe. Romy has a slightly flared, semi-fitted silhouette with bust darts. The square neckline is finished with a deep facing, and you can choose between shoestring or wider straps.

Sizing: AUS 6 – 22 (approx. UK 8/10 – 24)

Fibre Mood Uzma Top

Uzma is minimalistic, but perfectly finished - a timeless garment that goes with many outfits. This square neck top is cropped (though the length is easy to adjust) and lovely and loose. The neckline and armholes are finished with an all-in-one facing, so it's nice and neat inside. Depending on the size you are making, you could even squeeze it out from 1 metre of fabric.

Sizing: XS – XXXL (approx. UK 6 – 28/30)

Itch to Stitch Islares Top

Jersey lovers, this one is for you! Designed with both comfort and style in mind, this knit top features a unique squared neckline that adds a touch of contemporary flair to your everyday look. The pattern includes options for short, 3/4 or long raglan sleeves with shoulder darts. Regular and full bust options will help you achieve the perfect fit. 

Sizing: US 00 – 40 with regular and full bust options (approx. UK 6/8 – 34/36)

Helen's Closet Reynolds Top and Dress

Reynolds is your go-to squared-neck summer garment! Pair the Reynolds top with high-waisted bottoms or even sew a co-ordinating set. Reynolds features wide shoulder straps which are handy for hiding bra straps, and is shaped with bust darts. The pull-on overhead design makes this a true throw-it-on-and-go piece.

Sizing: US 0 – 34 (approx. UK 6 – 34). This pattern includes two size options. There is a B-cup pattern for sizes 0 - 22 and a D-cup pattern for sizes 12 - 34.

Friday Pattern Company Square Neck Top

If you like to float between knit and woven fabrics with your sewing projects, this might be the pattern for you. The Square Neck Top is a boxy, slightly cropped, dolman-sleeved top with a square neckline. A great beginner sewing pattern, it includes pattern pieces to make the top from a knit or woven fabric, as well as front pieces drafted for an A/B cup or a C/D cup. I couldn't resist batch sewing this pattern when I first got my hands on it, and I have used the lovely neckline to hack other patterns!

Sizing: XS - 7X (approx. UK 6 - 34) with A/B and C/D cups.
