Love this nearly as much as the other one - I swim a lot and having the two of them is perfect. It fits really well. Am size 16.

Great colour - however - the bottom half shows any tattoos/poor decisions you may have made in your early 20's . The straps are a bit on the thick side to give full shoulder mobility for longer swims.

Wore this for the first time yesterday- it’s so much better than it first looks. Colours almost ‘shimmer’. Good fit for pool and lake swimming. Being 180cm tall I don’t usually have much success with swimming costume length but this one is fine- just go up a couple of sizes for length

Love my new costume. Ordered on Wednesday costume arrived via Amazon on Thursday ( good delivery choiceSG). Unfortunately wrong costume arrived. Alison at Stolen Goat sorted this out the next day and the right costume arrived on Saturday. Excellent service and thank you. Sorting out problems is how you really find out how good a company’s customer service is. Only problem now is deciding which one to wear as I now have all 3 designs 🧐

Feels great - I sized up. Needs a bit more liner in the bottom half, but I feel great in it.

Really nice swimsuit- fits well, and lasts well too. I have two of these now and use them regularly, they last much better than some of the 'big' swimwear brands.

So classy , I love this swimsuit . I previously bought the Upstart design for use under a wetsuit , but this design turns up and I had to buy it . Same fit as the others so tall ladies will need to size up for length , but I gather thats the advice. I'm under 5 feet tall and its perfect . No bagging and stays put . The design is great , both colour and shape . The shoulder straps are quite tight on me but you know there wont be any incidents as you swim , it really wont move . The pattern is elegant and just bright enough if you aren't into bold patterns but don't want the usual black . Stolen Goat have succeeded again

Fantastic swim suit in design and material. However, the image made me believe it had a higher hip position and covered less of the bum, which I prefer, however it’s a full bum and low hip/thigh placement. The sizing also comes in very small. I ordered a small to give room for my bigger butt, but the whole suit is very tight. Still fits me so I’ll keep it, but I’d have preferred it a little looser. I’m 5’1, 48kg and usually a 6-8.

Ordered myself one ‘by mistake’ . Colours are bright and fabulous. Size up if you’re tall. I’m size 10-12 but wear size XL for length as I’m 5’11”/180cm tall. Fit is perfect for sport swimming- leg cut isn’t too high and good inner bra shelf. I have all 3 colours so definitely recommend

Such a lovely bright costume . I bought this to go under a wetsuit as my current costume has raised piping on it and is uncomfortable as a result . This fits really well , a close fit with no bagging and I love the firm back straps with no chance of it moving out of place . I am 4'11''and bought the medium based on the sizing chart and my usual Stolen Goat sized kit . The length works perfectly for me , but I can well see how tall Ladies will find this more problematic as others have stated . I might need another colour now too

This is the second SG swimming costume I’ve bought- one for me one for my daughter. Good quality, great ‘stand out ‘ design and extra bra support (invisible from the outside). Now I want the last design! We’re both tall ( 5’11”) so sized up a couple of sizes to get the length- perfect.

Brilliant swimsuit! Love the colour & pattern. I’m a 12 and ordered XL otherwise it felt too tight but if you want it tight for competitive swimming L would suffice. The lined bust area is a plus. Have matching towel and cycle gear too! Washes well.

SG swimsuits are fantastic. Flattering cut with a supportive shelf and comfy straps. Sit perfectly under wetsuits too for OWS adventures but punchy designs to help you stand out at the pool. Love this design as I can have a matching towel too. The pink swimming cap goes well for full SG ensemble.

Loving this costume. Colours are bright and ‘standout’- using it for regular river and sea swims ( and the occasional dip in the hot/cool tub. Colour hasn’t faded with regular use. I’m a normal size 10/12 but being 5’11” tall I ordered size XL for length - size is perfect.
