Not a big deal at all, but curious what others would do...

DD1 and DD2 need some new cartwheel shorts for wearing with dresses this summer. They will be 5 yrs and 3 yrs old, and can pretty much wear the same size. DD1's 3Ts from last summer still fit her, but the set DD2 wore last summer were all like 12m or something crazy, so they really don't fit her anymore. I was all geared up to buy DD1 some new ones, and pass hers down to DD2, but then it hit me that maybe I should just buy new ones for DD2 instead (she'd probably wear them a second year, so ultimately they'll get the same amount of "use" no matter who I buy for).

The only downside to buying for DD2 is that I'd likely buy the same size as DD1's old ones...meaning that if anyone other than me does laundry, they're going to be really confused!
