My dd is getting some riding lessons for her birthday -not a lot but its a start and all we can afford and I am very and so I want to get her something to open on her birthday and I though some cheap jodphurs but blow me they all come in inches size... she is an averageish (slightly small height wize but not fat not skinny) -any suggestions to " - don't want to take her to a tack shop to try some on as that would give the game away
