I always use my dolfin uglies and love the way they look but this time I ordered my usual size and the bra  part of the swim suit is way too small I looks like they used 1/3 or 1/2 less fabric.  The bottom fits perfect!!
I haven''t put any weight and it barely covers me on top!! It looks that they made the suit for an 10 year old  !!
I will take pictures so you can see the difference from two dolfin uglies!

I bought this 2 pc coz my friens makes fun of my tan lines wearing 1 pc. So after reading all d reviews abt this product I decided to go 1 size up and they were right abt the top being too small coz I have a very flat chest. Its good overall the only thing I can complain abt is the top it does hug your chest its kinda of fluffy for me or maybe i"m just too small.

Bought this bathing suit for my13 year old daughter, bought her one just like it two weeks prior.  She loves how comfortable it is, how it doesn't shrug or move.  If you have any chest at all this is not the bathing suit for you.

In reality this suit is a little too big, but it was purchased for a tween girl.  In my opinion, the bottoms especially look too small to be designed for most adult females.
We tried on the small at a swim meet and it seemed right but after swimming in it I could see the top was too baggie for my tween.  Even bottoms might be ok in a smaller size.  She normally wears about a sz 24 or 26 depending on brand for a 1 piece suit, but is more narrow on top and that is probably the difference.  I may buy another in an XS because I think these are so cute and more appropriate for a tween girl bikini than what you see in clothing stores.
We plan to hold onto this for next year assuming she'll grow into it and I can tell it will last due to the material it's made from.

Bottom fits well, top way too small. Should be able to mix sizes.

I am always impressed by Uglies quality, so I want to give a try for myself (my 7 year old daughter wears Uglies for her swim practice). Since several reviews mentioned sizing issue. I ordered L (based on their sizing chart, I should wear medium, my dress size is S). Bottom fits all right, but top fits very strange. It seems to me straps are way too short, front cuts low, doesn't feel tight on my chest. I feel medium may fit better on my chest, but may be too low in addition to shorter straps. I return it, even I really like the color and quality.
