Right Nina Ballerina Flat (Women)

I've been wearing the Right Nina style since about 2009, many different colors over the years. I am a 37 in Dansko, a 7.5 in most American brand sneakers, and always, always a 38 in the Right Nina. So I ordered the light pastel grey in a 38, not thinking much about it because they have been so reliable. Well, they just arrived, and they are just-enough-too-short that I can't make up my mind about exchanging for a 39 or keeping these and hoping the leather stretches. I mean, they are really only about 1-2 mm too short! So I don't know. Formerly, loved them; have recently bought the black with purple elastic straps in 38 and they were fine, and bought the black ghillie style in 38 and they were also fine. I'm inclining towards keeping these, but thought this review, rambling though it is, might help someone.
