I really love this dress and the yellow is an amazingly bright color that’s perfect for the summer.
I purchased a size Small but I think a Medium would have fit a bit better around the bust area. All of my other dresses are smalls and I usually base the size off of my waist.
The fit was a bit tight around the bust and underarms but not enough of a deal to return. I have a larger, more pronounced rib cage and I do feel like that went into account.
If you want a more comfortable fit and have a larger bust, I suggest basing this dress off of bust size measurement.
For reference, I am 36in bust, 27in waist, and 37in hip.
