This ended up being a very awkward dress for me. I purchased an XL to fit my 40" bust, but somehow this dress was both too small and too large. It is very stretchy, and I like the pattern and I would have hemmed the bottom to make it more flattering.
Somehow it made my boobs look as flat as in middle school. There is a strange seam in the waist area that crawled half way up my boob to make it look like they started there. MAYBE a pointier bra would have helped.
Then it billowed out to make my tummy bigger than it is, again starting from high under the boobs.
I just don't know if I need a Smaller size to grip under the breasts and not crawl up.
Same with the neckline, I like the V cut flaps, but it crawled up my neck to make the dress super funky looking.
So maybe it does need to be smaller to be held down, but if that doesn't work then a smaller dress will be pinched up around my chin and the elastic part over the top of my boobs.
Over all I wish I could try on a few different sizes to see what works, and if it works. I'd love to have a comfy, stretchy, pretty dress.
