Maysen Hi-Lo Dress by {SIG}creations

Maysen Hi-Lo dress, sizes 12m-5
Tween Maysen Hi-Lo dress, sizes 6-14

This dress is adorable! And it has a ton of options - 4 sleeve options, you can make an empire waist with or without elastic, a sash, or a ruffle along the hem. As with most of Astrid's patterns, you can mix and match with some of her other patterns to get a totally different look.

Paige dress by {SIG}nature Creations

If you're looking for a quick sew, the Paige dress is it! It's really more of an upcycle, since you can use a pre-bought shirt to make it. It ranges in size from 0-6 months up to a 13/14. And as an added bonus, a tutorial for the headband is included!
You'll have to forgive the less than stellar photos. I tried twice to get pictures, and baby girl was less than cooperative. It was probably due to the double ear infection and thrush.

Poppy Maxi dress by {SIG}nature Creations

My newest designer to test for is Astrid from {SIG}nature Creations. Her Poppy maxi dress is beautiful! It comes in two separate size ranges, Girls (12 months-5) and Tween (6-14). I tested this in my Diva's size.
