What do you think?

Mom, what do you think of this shirt/top I made for Coley?  I found the pattern/tutorial on Pinterest however she has you measure around the bust of the child to make the main piece.   One problem...how do you get it over their shoulders?  I have to pull it up so a friend suggested that I put buttons on the back of the straps instead of sewing them in.  I'm afraid it won't fit her by summer time. :( but I think it's cute.
