Can you help me find something like this please?

[Stripypopsicle]

I will attempt to attach a picture. I am looking for something like this and am not sure what sort of search terms I should be using.

I am trying variations of handmade ruffle outfit and similar.

I particularly like the ruffles (is that the right description?) sleeves? Cuffs?

Any help is greatly appreciated!

Elasticated ruffle cuff

Search for romper. I found this one at Matalan

There are lots of similar looking outfits on childrensalon if you look under baby-outfits-traditional outfits of course it will depend on your budget as some of these are pricey.
