Wellfleet T-shirt

I absolutely love my 2 Wellfleet T-Shirts I've made to date!

I've made some modifications which you'll find more of here: https://www.instagram.com/p/DeWZecoALTR/?obrf=ZXZyMndqazNmcms3

This is not just a t-shirt, it's a runway t-shirt! I've made a few "cup sized t-shirts" but the Wellfleet T-Shirt is by far the best!

I'm already planning a short sleeved version for summer here in South Africa!

Thanks for an awesome pattern!

Wellfleet t-shirt

I love the T-shirt, and it fits! I used a size 18 for the shoulder, neck, and sleeve area, a size 20 for the bust, and a size 22 for the hips. Best fit ever. I still need to move the shoulder forward, but it fit. I have received so many compliments every time I wear it. I want to experiment with a slightly lower neckline. Already planning on my next make.

Wellfleet Tee

What a nice tee shirt! The boatneck makes a nice change of pace. I also liked the notch in the sleeve and the split hem at the bottom. It’s one of my new favs.

Wellfleet tshirt is fantastic

What a wondeful easy tshirt to make. The notches on the cuff and bottom hem elevate the look and the instructions are very easy to understand.

Wellfleet - a new favourite

I have made three Wellfleets so far and expect to make more. The pattern incorporates elegant features like hem and cuff slits to create an elevated wardrobe basic.

Great fit for Wellfleet

I ended up with a well fitting tee. I started out with a slightly lighter weight knit than was called for, (silly me I should read the directions first) but it worked out in the end. The side slits were easier that I expected. I lowered the neck because it was a little tight on me, a problem I always seem to have. Felt tight but did not look tight. Otherwise it was easy to put together and I am really happy with it. I even did some stripe matching.

I’ve made one and it’s love. I need to make another immediately

I don’t usually write reviews, but this pattern deserves the shout out. It’s the best boat neck pattern I’ve sewed and I love the details on the sleeve and hem. It’s a real joy to wear and I need more! I made the cropped length in 8EF. I removed the dart and instead added the volume back via the side seam (like the saybrook tank). The gently flared shape is really lovely. Great job Cashmerette!
