I am a magpie when it comes to patterns. Always into the new and shiny. I love the Jo-Ann pattern sales and just grab up tons of $1 Simplicity and $2 McCall's. But as I get more experienced at sewing garments for myself and my kid (all of my early, formal sewing education was costuming, so I never got much guidance in how to select and tweak patterns for my own body), I'm learning the value of TNT (tried and true) patterns and designers.
For me, I love Itch to Stitch. Kennis' block is just spot on for my body and her designs have a really classic, wearable aesthetic. The only changes I have to make are usually to add length (I like tops longer than most designers or RTW manufacturers for that matter, design them) and sometimes grade between sizes, depending on my body measurements. Likewise, I've found the perfect designer for kid dresses: Bubby and Me Creations (the designer of my all time favorite kid sew, the Ava Dress). Both designers have really clear instructions, with professional finishes and layered pdfs (this is HUGE. It means that you can print the pattern in only the size(s) you need. No more going blind trying to find your line where ten sizes converge!).
I've been lucky enough to test upcoming patterns for both of them as well. In fact, I've got some tester photos and a review of the newest Bubby and Me pattern for you now. Poppy is a knit, princess seamed dress in toddler to big girl sizes. It has options for long or puffed sleeves, or sleeveless with armbands. It has circle and gathered skirt options (I went circle for both of mine for two reasons. Number one is obvious: maximum twirl factor. Photo evidence to come. Number two is my own oddity, but I feel like I have a problem with my serger making gathered seams in knit waistbands appear in big bumps rather than nice gathers when I finish the waistband seam allowance so I just try and avoid them.). There's optional faux piping (which looks so slick and was super easy) and a ton of color blocking opportunities.
