Very professional! I appreciate how well the fabric squares have that random feel, but their placement feels well coordinated so nothing stands out uncomfortably. And I love the choice of fabric too - says fun, fun, fun!
i love, love, love it! Since when does an article of clothing have to be "practical?" If you love it and you love wearing it and you feel wonderful in it - that's all that matters! Wear it with pride! You did a great job with it!
I checked the information in my fitting book "Fitting Finesse" by Nancy Ziemann (great book by the way.) She says: For woven fabrics, the minimum ease requirements to ensure a garment fits comfortably without binding are: Bust - 3 to 4 inches; waist - 1/2 to 1 inch; and hip - 3 to 4 inches." So yeah a little big, but do a a muslin mock up or whatever first to check fit before cutting into your good fabric.
