There are three pieces to this collection; Haven Acres Blouse, Dressage Leggings, and Sweet Pea Cap. The top is a lovely peplum blouse designed for woven fabrics. It has a single button closure and elastic at the waist. The leggings are inspired by riding pants and have an insert in the inner portion of the legs. The legging pattern also comes with a standard version without the insert (like two patterns in one!). And then there is a sweet riding hat with little ears on it. I have to be honest here, even though this hat is sized so that most tweens could fit it, they may not want it. Abi thought it was very cute, but she did not see herself wearing it. (But one time she did leave the house in it and someone did give her a compliment.) My four year old did love it though depending on who else lives at your house, it may be worth the purchase.
Special materials required: For the top, just about any woven would work great and you will also need bias tape (home made or purchased), 1/4 and 1/8 inch elastic, and a button (optional). The leggings need knit fabric but the inner portion can be successful with a stretch denim or similar fabric if the outer leg is sufficiently stretchy. And finally the cap needs an outer fabric, a lining and super stiff interfacing for the brim. Some people used flexible cutting boards and I used an old plastic place mat instead and that worked great.
Skill level required: The top is easy but the hat and leggings require a little (not a lot) of skill. The inserts in the leggings require some easing, so I would not pick this for my first knit project. But, it is not that hard and a confident beginner could tackle them with success. The hat is not complicated, but it does require accurate and straight sewing. So again, not a project for first time sewers but with a few garments under your belt you will do just fine.
Good: The pattern instructions were very clear and easy to follow. There were colored pictures and lots of diagrams. She writes clearly and I did not have to read the instructions over and over. I love the style of the Dressage leggings. The fit was excellent and I think there are lots of fun ways you could use color blocking or mixing of textures with this pattern. We decided on one with bright colors and one that had a navy knit on the outside and navy stretch denim on the inside. She wears the navy ones quite frequently.
Bad: Abi is not a big fan of the placement of the elastic on the top. I think she would prefer it to be lower and we both would like the top to be longer. These are easy adjustments and are a matter of taste though.
