I had never heard of Jacqui Ainsley before, but apparently she is a British model, she is engaged to director Guy Ritchie, she has a 13 month old boy, and she is pregnant yet again. That is all of little interest to most of us, but what is of interest is what she’s been wearing during her second pregnancy. She seems to always look incredible, but also so very comfortable.

Jacqui particularly caught PF’s eye when she stepped out this past weekend in this lovely pair of silk pajama trousers and a simple blue cowlneck top. I just think she looks fabulous, but not in the least bit overdone–simply the epitome of casual maternity chic.

Jacqui’s loose-fitting printed navy trousers have a drawstring waist and are generous through the hips and thighs, but still manage to be slimming as they taper down to the ankle. Obviously, her sky-high blue platform heels don’t hurt the look either, but i think she could have worn flats and looked just as chic. I can’t locate Jacqui’s exact pant, but Sea NY makes a very similar looking patterned silk pant with both an elasticized waist and a drawstring, which are the two elements you need to make sure these are completely maternity-friendly. Not to mention how postpartum friendly these pants can be–British actress Sienna Miller wore the Sea NY Cravat Print Trouser this past weekend, just three months after giving birth (note the flats). I know she is a celebrity on the red carpet, but Sienna’s outfit looks almost doable for the rest of us, doesn’t it?

Sea NY has been a go-to brand for me postpartum, as all of their pieces are all designed to be…well, relaxed. The Cravat Print Trouser is priced at USD $375 and still available in all sizes at Matches Fashion.
