What CLs are you wearing today? (II)

How does sizing run in this style compared to other CL shoes you own? What size do you take in other shoes? I'm normally a 7 but I have 37 and 37.5 CL heels but both still feel a little tight after a decent amount of wear. Considering getting a 38 in these but concerned they might be too big. Thanks for your help!
I am so sorry for the late reply. Well the flats do run smaller. I have a size 35 but I shouldve bought 35.5 but its too late to return them so I was stuck with them. I think going up a half size of your normal wear will be the best option.
