I used to have a bathing suit from Aubade, it lasted quite well. Think the French lingerie brands in general are quite good for swimwear. I've never bought from Princesse Tam Tam though, but they are very popular in France itself.
The ozzies on here should be experts on this surely? I think Seafolly is always well regarded for a good flattering stay put suit that are a touch pricey but not outrageously so.
I'd been looking at the preview for the new Uniqlo U range earlier this week, Flo, but couldn't quite discern what was new apart from a pair of shorts that intrigued me but seeing them on the model I think they're going to be far too long and wide for me. The rest seems to be mostly basics or already sold out.
I did manage to snap up a TKmaxx bargain yesterday, a denim utilitarian jumpsuit just days after deciding I'd like one. Only €32 and from a Parisian brand I hadn't heard of before, Lab Dip Paris. It's cropped but weirdly is the exact same length on me as the model 
Did you manage to get the western jacket Elle, saw very similar looking western belt Emanuele Alt wore with it at ba&sh and tried on some western boots at Mango (in leather) that I really liked as they were well fitted at the ankle and not too high but they cut my leg off at the wrong point, probably a better fit for longer limbs. Sorry can't link, have attached a pic.
