My current weight is 170 pounds, my bra size is 38DDD, my arms aren’t small but aren’t big either just in the middle. I don’t like tops hugging my body so I always size up, but with this particular style because of the tiny zipper that it has at the back,I would definitely suggest you size up, at least 2 sizes up if you don’t want your stomach to show and if you also don’t want that extreme fitted look. Because I do have high waisted jeans my belly button would probably show a little but my stomach won’t be extremely out just my belly button will be showing a bit. Compared to the other blouse this has barely any stretch to it. It’s very beautiful and the zipper does give it a different vibe but In a good way! Material didn’t feel cheap so I would definitely recommend buying this! Follow me on ig at queen_ck10 to see how I styled up this top!
